Level Up At Intimacy 5



""You fight (the aliens) with giant robots made of weaponized love." "

- Ben Lehman, author of Bliss Stage

There are a lot of games out there that want to encourage relationships, romance, and sex between the characters: a game where you Level Up At Intimacy 5 actually makes your character stronger or gives them additional capabilities for doing so, usually by having increased Relationship Values correspond exactly to combat modifiers - say, Intimacy Dice in Bliss Stage or the powers of your various Personae.

Usually, the explanation for how hitting on people could possibly make you more powerful is that your Applied Phlebotinum weaponry is powered by intense emotions; sometimes this is coupled with the idea that you're fighting a Being Of (Im)Pure Thought.

The purpose of this trope is to encourage a player to take romantic and sexual actions, making it a trope specific to games -- a sort of literal interpretation of Friends With Benefits. Dating Sims love this trope, for obvious reasons.

A subtrope of Deus Sex Machina. Can involve Power Perversion Potential. A weaponized verson of The Power of Love and The Power of Friendship. May or may not be Intimate Healing. The opposite of Virgin Power. Often used with You Lose At Zero Trust. When being a Casanova is more effective than being a Dogged Nice Guy, that's More Friends More Benefits. Compare Optional Sexual Encounter.

Adventure

 * In Turgor If you open Sister's hearts, they will allow you to go in their chambers and travel to other sisters. It is also implied that the chambers of a happy Sister give more Color. However it is heavily subverted

Hack And Slash

 * If you marry someone in Dynasty Warriors 6: Empires, you can "rest" with your spouse, which levels you up.

MMORP Gs

 * Firan MUX has recently inputted a system where you get a temporary buff to your stats if you sleep with a whore while stationed at the front during war season.
 * Latale has a marriage system, where a fully intimate couple gets a 10% boost to their main stats, and with some special items give access to unique skills like summoning your partner, a full heal, and an experience boost.
 * In Ragnarok Online the Alchemist job can create an Homunculus, a fighting pet which has an "Intimacy" indicator. Once it gets past a certain level, the Homunculus can be evolved and gains access to a powerful skill.
 * Married characters gain unique abilities that work exclusively on their partner. Couples may also adopt a child character which unlocks similar abilities.

Real Time Strategy

 * In the Galaxy Angel game verse, your relationships with the Angels makes them stronger, and inversely, they like you more the better they do in battle. Insulting them makes their stats drop, and if you let them get blown up, they hate you.

Roguelike

 * Nethack players can receive substantial good or bad effects from sleeping with succubi or incubi, but with proper preparation they'll almost always be positive. This includes permanent stat gains and instant level ups, and if you have a method of generating many such demons can be used to vastly inflate your max hit points even after you reach level 30.
 * Dwarf Fortress is a partial example. Dwarves gain skills by hanging out with friends and lovers, and skill boosts will arbitrarily make dwarves stronger (even though this makes no sense for social skills). Thus, that dwarf that slouches in your dining room all day partying and making friends with everyone could very well be more dangerous than your elite military.
 * That is, untill one of the said friends die. At that point, kiss your fortress goodbye when your elite dwarf goes berserk...
 * ...and kills other dwarves, which, of course will cause OTHER loved ones that go berserk over their deaths, which causes MORE death, which in turn causes MORE madness, and so on in a descending spiral of blood, vomit, and carp...
 * ...and magma. It's not truly a tantrum spiral of doom until someone accidentally floods the entire fort with magma.
 * Mostly averted now, since skills only raise related attributes, but you still get such gems as fishing, studying, medic skills, and book keeping improving a dwarf's accuracy with a crossbow and Intimidation and Comedy letting a dwarf run faster.
 * Which makes sense. A high Comedy skill improving speed clearly makes the Dwarf a Running Gag.

Role Playing Game

 * Shin Megami Tensei: Persona 3 is a definite example - the various Persona you can use grow stronger as you strengthen your relationship with the character who is associated with the same Tarot Motifs. In the case of female characters, that relationship tends to be romantic in nature. In order to create the Ultimate Incarnation of each Tarot, you need to max out your relationship with that person - of course, that also means that if you want a good lineup, your character is going to turn into a real Casanova, since he'll have to win the hearts of five different girls in the same school...
 * AND you win the affections of 2 girls who you can't actually have a relationship with (a and ). And in Persona 3 FES you can, although she's not a social link. Talk about the living incarnation of studliness...
 * Persona 3 Portable adds in a female protagonist, who can choose out of 5 options (Akihiko, Shinjiro, Ken, Ryoji and Theo) along with crushes from Bebe and Hidetoshi. She can choose at specific points if she wants to date someone, ala Persona 4. And for the guy, there's no consequence for dating multiple girls, ala Persona 4.
 * Persona 4 continues the trend but applies it to your allies. Odd-numbered Social Link ranks add additional in-battle effects ranging from using follow-up attacks to taking lethal attacks for the MC, while the Personas of your allies will only mutate to their final forms once you have fully maximised that person's Social Link. In that game you don't have to raise the females' Social links romantically (thus you can remain faithful to one girl); though choosing the romantic route will show different scenes.
 * Devil Survivor 2, another Shin Megami Tensei spinoff, features the Fate System, which works similarly to the aforementioned Social Links: reaching ranks 1, 2 and 4 bestows additional benefits to the character in battle, while ranks 3 and 5 unlock new demons for fusion.
 * Thousand Arms combines RPG gameplay with Dating Sim aspects. The more the girls like you, the stronger you get!
 * Neverwinter Nights 2 Mask of The Betrayer goes and makes the only romance in a Bio Ware/Obsidian title that would be unforced give you a feat for finishing it (The male PC romance plot also gives a feat, but it still has the other issues).
 * The non-romantic relationships also give bonuses. For example, maxing out the bear Okku's respect for you causes the Hunger Gauge to deplete much more slowly.
 * In Baldurs Gate II: Shadows of Amn, romancing Jaheira the "right" way gets her a Harper Pin, which grants several useful bonuses. While better replacements show up near the end of the game it's a good item for most of the mid-game. More importantly, however, successful navigation of this quest (which is not actually part of the romance, but gets powered up if you're in a romance with her and weaves in and out of it), nets you a few large buckets of experience points. The trope is inverted (though it's perhaps more of an oversight) in the expansion pack Throne of Bhaal, where if you're romancing Viconia you can ; doing so prevents her from using a very good item that she's already wearing--and she doesn't get a replacement to reflect the change.
 * She still gets better off then she would normally in the Forgotten Realm setting: Usually, a cleric of Shar turning neutral would lose ALL divine abilities and spells, not just one item.
 * Debatable. Shar had a fairly obscure order detailed in Warriors and Priests of the Realms (2nd edition splatbook) that venerated her as a deity of sleep and dreams, and was TN - even having an option for NG priests.
 * Planescape Torment is a strange case. You can get useful items or stat increases from, or confer stat increases to, almost all your party members by talking to them. The only real exception is Fall-From-Grace, who in a more conventional game would have been a potential romantic interest, but she can help you understand your party members better, cluing you in on which dialogue options to take--and also doing so earlier than the game would normally allow. Annah, meanwhile, is deeply attracted to you; you have the option to kiss her at one point, and it boosts her morale--until she gains her next level, where it returns to normal, possibly due to a bug. (For context reasons, let's now reveal that Grace is a chaste succubus and Annah is descended from fiends.)
 * Not a romance, but Dakkon's karach ("chaos-matter") blade becomes more powerful as he levels up. However, how it becomes more powerful depends on how he feels about you. If he finds you honorable and worthy of his service, his blade becomes an excellent defensive weapon; if he hates you, this is reflected in his blade becoming vicious and serrated; if he has no real opinion one way or the other, it's a balance of the two. This means he's probably better as a pure melee fighter when he's angry at you...but if he gets angry enough, he will attempt to kill your ass.
 * Not a romantic example (in most cases), but there are a fair number of Pokémon who will only evolve if the trainer keeps them happy and builds a strong relationship with them.
 * Also, the move Return gets stronger the more the Pokémon likes the trainer. The reverse is true with the move Frustration.
 * A handful of NPCs will teach moves to a Pokémon only if it loves its trainer enough, or give the Pokémon a ribbon, or will give you an item if the first Pokémon in your party loves you enough.
 * In Knights of the Old Republic II, you can train certain characters as Jedi if you get your Influence score with them high enough. Even characters who can't become Jedi still offer other bonuses, such as experience points and stat boosts.
 * Ar Tonelico is a series of pseudo-dating-sim-esque RPGs practically built around this trope, as you gain most of the game's musical spells by "diving" into the female characters' inner mental worlds and helping them fix their issues, an act which the game specifically links to romance. Furthermore, the characters' power in battle is increased by "Harmonics", a set of two gauges which represent the feelings of the fighting party and the magical songstresses respectively, which add status boosts to the party when the bars meet in the middle; the bars increase when the fighting party defends your singer-mage, attacks on her behalf, or does something otherwise suitably impressive for her.
 * Incidentally, "diving" at level 5 and beyond is when things get (supposedly) dangerous. And any and all innuendo before this is blown out of the water
 * Subverted in Wizardry 8, where it's Level Down At Intimacy 5.
 * To elaborate, you gain the trust of the Rapax Templar by making one of your party members an initiate. As the final task of this ceremony, the character must make a "sacrifice" to their demon queen, which basically means that the initiate (male, although she will take a female if the party is entirely composed of women) has to sleep with her. The bad part is that the lucky guy ends up permanently hexed and suffers massive stat loss if he ever leaves the Rapax Ravine until the demon queen is killed. As if that weren't enough, if you actually go through with this, it makes the already tough fight with the Rapax prince harder as--in addition to his entourage--he'll also be accompanied by the daughter of the demon queen and the character that slept with her. While this all sounds like a raw deal, being a Rapax Templar does have its advantages, and can lead to a really awesome quest down the line.
 * In Star Ocean (really, any of them), various bonuses you can pick up from having good relationships include (in the second one alone): special techniques, random items, improved item creation, and if in battle, doubled attack power.
 * Having a good rapport between your party members is essential to teamwork. For example, in The Second Story, if you choose to have your B team fight, it's likely the AI-controlled members will just do their own thing, even if they are assigned to healing duty. If Noel doesn't particularly care for Dias, he'll probably take his sweet time casting Dispel to cure Dias' paralysis.
 * In Mana Khemia Alchemists of Al Revis, Roxis won't be able to learn some of his spells unless you follow his character quest up to a point, and he won't be able to participate in Co-op Synthesis unless you follow it further. No other characters' abilities are affected by their character quests, but your Variable Strike gets stronger as your Relationship Values with the participants increase.
 * Also, if your relationship isn't high enough with any of your teammates (if you haven't finished their character quest and talked with them in the final chapter) you'll end up with the bad ending as
 * Valkyria Chronicles, while not elaborating much on romance between the various secondary members of Squad 7, has the abilities 'Fancies Men' and 'Fancies Women', which increase a character's effectiveness when around males or females, respectively, because they want to 'show off'. Yes, there are female characters with 'Fancies Women' and males with 'Fancies Men', and even one who has both of them. Also, one (female) character gets an extra boost around the female lead.
 * While you don't actually level up from it in Dragon Age: Origins, you do gain influence - and can lose it, too, based on your actions. Sufficient influence with a member of your party grants them bonuses from the inspiration your character provides them. Negative influence, on the other hand...
 * Dragon Age II follows the suit by giving your Companions unique bonuses/passive powers upon reaching high levels of either Friendship or Rivalry, such as the shieldmaiden Aveline taking 10% damage for Hawke if her Friendship was maxed out.
 * In Raidou Kuzunoha VS King Abaddon, your Mons will gain a new skill when their loyalty is maxed out. This is the primary method of gaining passive abilities, which are sorted differently from attacks.
 * And the more Loyalty you gain, the higher Raidou's Rank becomes (some ranks are just awesome: Morning Star, or Taisho Examplar), but also: at certain levels, Raidou is gifted with more tubes, allowing him to hold more demons.
 * In Monster Rancher 2 (not sure about the other installments), your monster's relationship values have a major game mechanic effect. Monster with low Loyalty are much more likely to fool around during fights, disobeying your commands and leaving themselves open to attacks. If a monster gets too spoiled, it will often refuse to do its training exercises, while a monster that fears you too much gets stressed out (shortening its lifespan) and is likely to run away. How you treat your monster can also affect its Good-to-Evil axis, which both affects its behavior and its access to certain techniques.
 * Alpha Protocol gives you "perks" for getting into bed with various women which adds a couple of in-game benefits. It also gives you experience points, so it's always funny to see Mike level up just after doing the dirty. Oh and the game has six achievements based around sex - five for having a good night and one for abstaining. You get perks whatever you do. Perk list
 * In Mitsumete Knight R: Daibouken Hen, you gain access to powerful magic spells if one of the two female partners of your party has very high Relationship Values with MacLeod. If both of them are in love with him, you get even stronger magic spells, one of which being a rainbow-colored Kamehame Hadoken.
 * Fallout 2 subverts this. You can have sex with a girl or guy and marry them, but they're nearly useless and difficult to get rid of.
 * Mass Effect: If you don't want the ending of the second game to be a complete bloodbath, you'd better max out the loyalty scores of your squad. However, doing the actual romances does not bring any gameplay benefits to Shepard or his/her partner.
 * Building a healthy rapport with Yeoman Chambers gives you the option to have her feed your fish, so they don't die if you forget to do so after every mission.
 * In Septerra Core you may lead lead Grubb and Led to start a romantic relationship witch each other, which rewards both of them with unique special attack.
 * In Criminal Girls, you can use Punish Mode to teach party members new moves. (Battle moves, you pervs.)
 * In Xenoblade Chronicles, raising the affinity between your party members allows them to equip each other's skills, increases the effectiveness of chain attacks in combat, and makes it easier to craft high quality gems.

Simulation Game

 * Harvest Moon: A Wonderful Life requires you to betroth a girl and have a baby in order to advance the story.
 * AWL (and AWL: Special Edition) arbitrarily has the bachelorette with the highest affection towards you propose to you, if you aren't already engaged at the cutoff point (in this scenario; usually Celia or Muffy if you haven't gone after one specifically). You get a Nonstandard Game Over if you say "no". In the other games, wives raise your overall rating and unlock various items and events. (In the older games, you would get a failing evaluation without a wife)
 * If you don't marry in Rune Factory 2, then you can't play as your child and finish the game. Luckily, three of the prospective bachelorettes will never marry anyone but you and you have a few years to choose from all of them. However, the game does have a preferred marriage and none-too-subtly assaults you with images of First Girl Wins from the opening sequence onwards.
 * In Rune Factory 3, the higher your friendship/love points with a villager, the longer they'll stay with you accompanying you into dungeons (At the lowest level, they'll bail out after 5PM, then 8). Your wife will stick with you no matter how long you stay in a dungeon (VERY helpful when slogging through the last couple of Bonus Dungeons).
 * In newer versions of The Sims, Romance oriented Sims have as their main life goal to have as many love relationships as possible. This gives them happiness and points with which they can buy game-enhancing items. And, all jobs in the Sims require maintaining a lot of friendships to reach their higher levels.

Turn Based Strategy

 * In Sakura Taisen, the more one of the girls likes Ogami, the higher her stat bonuses. In addition, a high enough trust rating will unlock special attacks.
 * These include giant mecha that transforms from a theater.
 * And a hot springs bath that makes mecha explode.
 * Fire Emblem: Genealogy of the Holy War uses this with a twist: it's limited to romantic relationships, and in the second half you play as the characters' children. Their abilities depend on who supported with whom in the first half. The second generation characters can be paired up as well, but this only gives the usual stat bonuses since the game ends before a third generation can show up. Additionally, sometimes the partners in a relationship can give each other stat point increases or great items. Later games are similar, but that falls under Relationship Values.
 * Sengoku Rance, as well as the other games in the series, love this trope. As relationship goes up, characters get stronger, to put it in a simple way.

Visual Novel

 * The warrior Iris from Princess Waltz is formed from the combination of the Prince and a Princess, with her powers determined by the level of intimacy between the pair. Being one of "those" sort of games, the Mentor notes that sex can be very helpful in making the pair comfortable with each other's bodies.

Wide Open Sandbox

 * Grand Theft Auto San Andreas has this. Six girls you can date, in exchange for perks, like weapons, clothes, their cars, the possibility for dying/getting busted without losing all weapons, and, in one of the girls' case, a plot advancing MacGuffin for a mission.

Anime and Manga

 * In Lucky Star, Konata says that to her, building up "trust points" in the days before Valentine's Day is more important than the day proper.
 * In The World God Only Knows, the power of certain supernatural entities is directly related to the feelings of the host. Unfortunately, for the evil types, it's proportional to the host's negative feelings.
 * Persona 4 - the animation, following the video game source.
 * Digimon Adventure 02 provides a G-rated, non-romantic example: jogress evolution triggers for the first time when the Mons' human partners bond in such a way that "their hearts beat as one" and they gain a deeper mutual understanding: Daisuke gets through Ken's Ineffectual Loner attitude by telling him You Are Not Alone, Miyako delivers a Get a Hold of Yourself Man to Hikari, and Iori begins to understand why the forces of evil are Takeru's Berserk Button.

Comic Books

 * Scott Pilgrim - It's worth 9999 EXP and a free perk, anyways.

Literature

 * Anita Blake books are a literature example. In Anitaverse, a triumvirate of a vampire, a lycanthrope, and a necromancer gathers a big power boost over the sum of their individual powers. The catch it, to gain the boost, all three have to be very fond of each other. A triumvirate doesn't have to be menage a trois (although, it implied, it often is), theoretically the triumvirs could just be very close friends.
 * Literary example in Tanith Lee's novel Lycanthia. The feudal lord of a certain lineage, when having two werewolf companions, gains the magic powers of an ancient wolf goddess - but only if all three are in a state of true love (not necessarily sexual). The powers are implied to be immense. The protagonist doesn't feel true love to his werewolves, just a kind of needy affection - but even that is enough to summon a hailstorm at a critical moment.
 * Near the end of Illuminatus, this has to be used repeatedly by one character to become an avatar of a goddess.

Tabletop Games

 * The tabletop RPG Bliss Stage is the Trope Namer: In that game, your primary weapon against nightmarish aliens is the Alien Numina Inversion Machine, or ANIMa - it uses Psychic Powers to create a Humongous Mecha for the player characters out of their relationships. 5, the highest possible score in a relationship, requires you to have sex. There is a drawback: Unless you also improve the relationship's Trust stat, the relationship could easily be broken off. And breaking a high Intimacy relationship is a Very Bad Idea.
 * Bliss Stage First and Final Act takes this to its logical conclusion: having sex with a partner gets you an Infinity Plus One Sword, with special abilities that break the rules of the (tabletop) game.
 * HeroQuest (the fantasy tabletop rpg set in Glorantha, not the MB boardgame) stats everything up, including relationships. Also, any stat can be used to augment any roll provided you can make a case for it to the GM, so your "love for kidnapped princess" score gives you a bonus to fight the dragon, and your "hatred of nuns" score makes it easier for you to kick one in the face.
 * Weapons Of The Gods has you improve your kung fu by consummating your love. However, it only works in heterosexual interactions - for homosexual interactions, you need a special kind of kung fu to improve your kung fu. It doesn't sound this offensive once you read the book.
 * To clarify, it's based on Taoism. Heterosexual intercourse allows for the unity of yin and yang, male and female, which is a major theme in Taoism.
 * Monsters and Other Childish Things places a heavy emphasis on relationships. Kids can draw upon their relationships to give them an extra boost when needed, like punching someone who insulted their brother extra hard, or doing better on a test if their mother encourages them. Monsters can also draw upon a child's relationship for an extra boost in combat, but if a relationship boosted roll fails...
 * Any Tabletop RPG in which the DM is in the habit of giving players extra XP for roleplaying can have examples of this.
 * Maid RPG has seduction built into the rules, and both sides benefit: The seducer loses Stress, and the seducee gains Favor.

Web Comics

 * The webcomic Pv P plays on this trope in this comic, where

Web Original

 * The web serial Memetic Narration (found here) features high school students who get sucked into a computer and fight turn-based rpg battles. Their available abilities are affected by their relationships with each other, so the main character (being the only one who knows of this) works hard to befriend each of his teammates.

Real Life

 * In Real Life, marriage (but not anything else) unlocks lots of special rights and financial bonuses that make it easier to get a high score and a better game experience (though Your Mileage May Vary on the latter). It also makes pregnancy and being over certain age much more acceptable. Won't  but makes you less pitiful during it.
 * Subverted: you often pay more taxes. And your significant other can often walk away with half of your shit.
 * In the United States, you tend to pay more in taxes if each of you earns a similar income. If you instead bring in all the money, you get to pay less.
 * It all depends on the server. All versions have some rules for it, but on some it's more necessary than others (especially for female characters), in others it's just a perk or a Self Imposed Challenge. Don't get us started on the Gay Option patch.
 * Now you can buy it in a patch?
 * To put it another way: marriage doesn't require Intimacy to be at level 5 in order to initiate, but having it at a high level makes divorce less likely, and regardless of what the players' intimacy levels were at the beginning, it may or may not end with losing half of your items and a lot of prestige (again, depending on server and current rules in effect).
