Artificial Stupidity/Video Games/Miscellaneous Games

These should be sorted into Artificial Stupidity pages for the various Video Game Genres, unless they're so weird that they don't fall into any classification.


 * Video games for Yu-Gi-Oh!! have a particularly poor track record in this area. While some of the games' idiotic moves can be justified by the fact that the AI couldn't possibly know the identity of your facedown cards, and that the kind of analysis that would allow a player to even make the right guesses can be really difficult even for human players, some of the cases are a little more obviously Artificial Stupidity.
 * Then you have Mokuba, for whom this trope is invoked intentionally. What a digital dummy!
 * To give you the idea of how dumb he is, his second strongest monster is Kanan The Swordmistress, a normal monster with 1400 ATK and 1400 DEF. He summons none of his monsters in defense mode, letting you just keep knocking them down. His entire strategy is to draw one monster, Cyber Stein, which has the ability to summon a fusion monster. This is the only way you can lose to him, cause if he does this, he'll summon Blue-Eyes Ultimate Dragon.
 * In many of the earlier games, such as Eternal Duelist Soul, at harder levels, the AI essentially knew the ATK and DEF of any of your facedown monsters, and would make its decisions whether or not to attack based on that. Some of the "good" duelists like Yami Yugi go at you with cards that technically can destroy yours in battle...and then leaves them right open to a strong counterattack when the player is able to capitalize on the fact that they left a monster with 1000-1100 ATK in attack mode at the end of their turn. Attack! Attack! Attack! meets Artificial Stupidity here.
 * The AI in Tag Force 2 is considered one of the worst examples of this in a Yu-Gi-Oh game, to the point where it seems like the game is actively trying to sabotage your efforts when you play a tag duel.
 * For instance you might have a monster that can't be destroyed in battle while it's in attack position, and a trap that stops all damage you take as long as you have a monster out, effectively making you invincible while that trap is out, as long as you don't switch that one monster to defense position. Your partner will switch her to defense position as soon as your opponent plays a monster with more attack then her.
 * The best example came from a Tag Force 4 video, when the AI used Prideful Roar against Clear Vice Dragon. The AI paid 2800 Life, took more than double that in damage, and promptly lost.
 * While the AI is occasionally competent during duels, it gets really bad during the minigames. For instance, Tag Force 2 features a 'dodgeball' minigame, it's basically a matter of using different forms of ammo to KO 2 AI opponents. Unfortunately, several characters are prone to standing directly behind your character and throwing a bowling ball (1 hit KO)
 * In Dark Duel Stories, the A Is have a bad habit of offering high-ATK monsters as tributes to summon something just as strong or even weaker, example: Offering "Jirai Gumo"(2200ATK/100DEF; it is interesting to note that this is the strongest LV 4 monster in the game, plus he is stripped of his detrimental effect) as a tribute to Tribute Summon "Catapult Turtle" (1000ATK/2000DEF). Might I also add the AI will also tribute monsters which have been equipped with two spell cards without hesitating, so if he powered up his "Tripwire Beast" to 2200ATK/2300DEF and also had Mountain activated, increasing the original ATK/DEF by 30% to a grand total of 2560ATK/2690DEF, it's not unsurprising for the AI to tribute it for a weaker monster such as "Morinphen", a LV 5 monster with poor stats (1550ATK/1300DEF).
 * The AI also likes to use monsters who have lower ATK than DEF to attack, as long as the ATK is at least half the DEF. Sometimes, Yami Yugi will use "Megamorph" (which acts like a universal Equip card, increasing a monster's ATK and DEF by 500) on Mystical Elf just so that he can attack... with 1300 ATK.
 * It's important to note that the AI in most Yu-Gi-Oh games varies from Cheap to downright stupid. When they're cheap, they're somehow able to see your hand and somehow draw the exact right card(s) to counter it...
 * Also, dueling the anime/manga characters, they can somehow see the defense of a face-down monster before it's flipped and will decide whether or not to attack it based on a stat it shouldn't know yet (of course, it'll sometimes wait a turn, summon another monster and then attack with the same weak monster they hesitated with anyway).
 * Another thing the AI will do, which can be called the "fake out dance" is to know a monster's high defense before it's flipped, but keep summoning monsters too weak to destroy it and apparently fake it out. Not too horrible, until they'll do this even if you have stronger offense monsters out. And they'll keep doing this until they lose.
 * There's also its inability to judge the worth of cards in its hands, meaning that it discards randomly whenever an effect makes them do so, which can often make them cripple their entire strategy by eliminating their most important card.
 * To wit: The AI has three cards, which consist of a weak monster, a strong monster whose level is too high to be summoned, and a spell which makes the user discard a card but would let him summon the stronger monster. The AI will, 50% of the time, activate the spell, discard the stronger monster, and then summon the weaker monster which wouldn't need the spell in the first place.
 * However, it's averted in later games, where the smarter computers will only throw out a strong card if they have something to revive it. If they have this strategy, they will use it.
 * Yu-Gi-Oh 5D's Duel Transer/Master of the Cards is also not immune. The AI Computer opponent you have unlocked initially has a few decks that are easy to overcome, but for some reason it likes to set off a combo of Waboku and Hallowed Life Barrier. I'll break it down: Waboku stops you taking damage that turn and stops your monsters from being killed, Hallowed Life Barrier is basically the same, except you need to discard a card to activate it, and all it does is nullify battle and effect damage, not protect monsters. I can see why it can help to prevent taking effect damage, but it's still a pretty stupid combination.
 * The AI is incapable of deciding whether or not using particular traps is a good idea or not. If your opponent has Torrential Tribute set (a trap which wipes all monsters on the field when activated), they'll use it even if the monster they already have on the field is stronger than the one you just summoned (of course if you're doing this, they might foresee your equipping it with something). Then again, they'll often wipe the whole field even if they have a much stronger monster out. Opponents using Torrential Tribute to destroy the whole field when they have a 2500+ ATK ritual monster out when all you did was summon a relatively weak monster is common enough to count as a strategy to get rid of their monsters.
 * Despite being the main character, Yugi will often make the baffling decision to keep summoning Sinister Serpent, an effect monster with 300 ATK and 250 DEF. It's effect is to keep showing up in his hand if it's destroyed. Good if you plan on sacrificing it, but he never does this. He keeps it out until you vaporize it with a much stronger monster, and then keep summoning it just because.
 * Total Defence Shogun is particularly weak in the hands of the AI. It has 1550 ATK, 2500 DEF, and it can attack while in defence mode. Whenever they play/use/control one however, they will always switch it to attack mode. So, basically, the AI weakens the monster by 950 points, AND opens themselves up to Life Point damage voluntarilly.
 * The AI will sometimes use Premature Burial or Call of the Haunted to summon Gearfried the Iron Knight. For those who are unaware, either of those cards can be used to summon a monster from the Graveyard, but the card is then equipped to the monster; if the card is destroyed, so is the monster it summoned. Gearfried destroys any card that is equipped to it automatically. Yeah...
 * Even more humorous because Premature Burial costs 800 life points to use.
 * The AI has also been known to do things like take control of your monster using a card like Change Of Heart, which takes yours for one turn, but then boost its stats with a permanent equip spell. So at the end of your turn, you get your monster back, only the AI has actually helped you.
 * There's a similar problem with the 1997 Magic: The Gathering: Duels of the Planeswalkers. Sometimes, the computer can come up with masterful combos and expert tactical plans. Other times: they sacrifice their last point of life to Pestilence in order to kill some Llanowar Elves, and summoning a Lord of the Pit and then doing nothing with it, meaning it eats all the computer's monsters and starts on the computer's life total. In particular, it will only attack if the creature is guaranteed to survive the creatures you have out or it has enough monsters to zerg you to death. This means that it doesn't, for example, fling expendable creatures at you to whittle down your forces, even if those creatures have a significant upkeep like sacrificing a creature.
 * In Yugioh: Dungeon Dice Monsters, any character not found in the anime will just summon around their Heart Points and will eventually use up all their summons. They will then be unable to do anything, allowing you to have a many rolls as you need to summon anything. The Exodia pieces can be summoned this way, and by summoning then all, you get an instant win, and the AI is powerless to stop you.
 * You can beat anyone in the game with an equally inane strategy. There are summonable "items" in the game which take the form of chests. Only the summoner knows what's in the chest, and it activates when a monster passes over it. The AI will never run over your chests, in the expectation that it might be a trap (and, to be fair, it might). However, it is possible, by spamming cheap summons, to block your opponent so that the only path to your heart points is through the chest. At which point, the AI will helpfully sit around, waiting for you to kill them.
 * The final boss of Magic: The Gathering: Battlegrounds has the ability to cast any spell in the game, any time he likes. Theoretically this means he should be able to spam you with giant monsters while countering any spell that you try to cast. Instead, he just sort of hangs around not doing much, and can be trapped in a loop by summoning the same low-level Mook over and over again. Possibly intentional on the part of the developers, since if the boss used his powers in a sensible fashion then he would be completely unbeatable.
 * This has plagued computerised Go engines (especially when compared with computerised Chess engines), with them being trounced by professional Go players even when given 25 stone advantages... The latest Go AI can win with a 9 stone advantage, and has been stated that it's up to good amateur levels.
 * In Go the problem space is much larger. While both go and chess have a finite number of moves per turn, determining the possible moves in chess is a matter of thinking of each piece and seeing where they can land and if it's open, whereas in go it's not a matter of "which of these 32 pieces can move where?" so much as "which of these 300-odd spots should pieces go on?", which doesn't just make calculation slower and more memory intensive, but also makes the heuristics harder to work on, too.
 * A classic computer game that has gone by many names over the years relies on this trope. In the original version, you had to run from robots, although modern versions have used zombies, vampires, Eldritch Abominations... basically, whatever. Anyway, you and the robots both move one square per turn (like a chess king), and robots will chase you down. You have no weapon, but the robots will attack and annihilate each other before they ever turn on you! Thus, you have to rely on robots' tendency to kill each other before they kill you.
 * It's even been done with Daleks.
 * The Windows program Mission Maker has extremely primitive AI. Make a character 'Seek and Destroy' the player, then get another character between them. The hostile character, instead of moving around, will kill the other character to get to the player.
 * The classic arcade game Berzerk allows you to make enemies crash into each other to kill each other. Or if you're lucky and clever, into the edges of walls.
 * Exploiting the Artificial Stupidity of the guards in Lode Runner is very useful, with some levels relying on it. For instance, you can position yourself on a ladder so they climb upwards when you're directly below them.
 * Golden Axe. Good game, comically bad AI. Enemies will often suicide themselves without your "help". The most effective way to beat Duel is to get 2 enemies on opposite ends of the screen and keep fly kicking off them, like a pendulum swinging left and right. Mario enemies are smarter than this.
 * In Splinter Cell Conviction, at one point you are confronted with an enemy helicopter gunship. It always shoots in front of Sam and never thinks to try and flank him.
 * The usual method to beat the last boss in Guitar Hero III invokes this. Basically, there's a certain point where a Whammy attack will kill him in one hit. Why is this? In that particular section, instead of using the whammy bar to recover, he just hammers the STRUM BAR until he kills himself. One critical flaw in an otherwise complete bastard.
 * Computer controlled helpers in Kirby Super Star have their uses, but don't expect them to live very long. Fortunately they're easy to replace.
 * Similarly, your AI allies in Kirby and the Amazing Mirror can be counted on for jack squat. They'll mill around in random areas, getting random abilities (including abilities not in their current area), and if you call them to your side...well, it's usually for one of three reasons: a boss fight, the fact that they bring health-restoring food with them, or one of them somehow snagged the Smash ability and you're just waiting for them to screw up so you can use it yourself.
 * If you've ever played a video game adaptation of a game show, you've probably encountered computer contestants that couldn't answer simple questions correctly. Press Your Luck for the Wii is one of the Egregious examples, with computer opponents answering questions such as "What animal do we get milk from?", "What is 36 divided by 6?", or "How many months are in a year?" wrong.
 * Old versions of Jeopardy! for PC in the early 1990's had the AI contestants buzz in and answer in complete gibberish. The answer pool was so small that pulling a wrong answer from that could clue the player in another time.
 * The above is true for the NES versions as well (save for Super Jeopardy!). However, the gibberish is the exact same length as the correct response, and often shows some letters in the response as well. For example, if a correct response is TV Tropes, the AI would show something like *V@r#pes.
 * Demigod, a Defence of the Ancients type game tends to inflict this on players when they go against the bots on higher difficulty levels. The opposing team will specialise in hit-and-run tactics, prioritise game-changers like Reinforcement Flags, and just generally give you a run for your money. Your allies, on the other hand, will position themselves directly between two enemy gun posts and pick on irrelevant minions, while being whaled on by the enemy, thus feeding your opponents both gold and experience. Since your opponents are now relatively stronger, and can afford to upgrade their defensive structures, this process becomes streamlined, resulting in ally deaths roughly every few minutes.
 * Star FOX series has wingmen's "calling for a help" as a fixed pattern in every side scrolling stages. They can't help themselves and will go down if you don't help them. All Range Mode, however, turns their stupidity up to eleven.
 * One particularly notable example of how bad the wingmen's AI is in All Range Mode is in the Star Wolf dogfights in Star Fox 64. Each Star Wolf pilot is programmed to target a specific member of your squadron. Each wingman will constantly plead for you to help him by shooting down the Star Wolf member who's on his tail. Once you do, he will blissfully fly around in a circle minding his own business and make no effort to help you as the remaining Star Wolf members continue to rip you and your other wingmen to shreds.
 * To be fair on that one, your wingmen destroying one of the Star Wolf pilots would screw you out of fair chunk of points, since things they destroy aren't counted toward the point total. Why they couldn't just let the things they do count isn't totally clear, but it's still better to have them do nothing than do something that hurts you.
 * The buses in The Simpsons Road Rage constantly crash into anything in sight without any provoking them, typically you.
 * in Portal 2 is a deliberate In-Universe example, described by GLaDOS as "the product of the greatest minds of a generation working together with the express purpose of building the dumbest moron who ever lived", and "the moron they built to make me an idiot".
 * Pokemon Card GB2 acts stupid in a lot of ways:
 * The AI will use cards such as Professor Oak and Bill a lot, and nearly always use attacks and other stuff to just draw more cards. And then run out of cards and they complain of losing...
 * They tend to play better at attack than defense and nearly always choose to attack even when it is not beneficial to do so (probably in a misguided attempt to pick up more side cards and win the game faster). Including the use of Defender at times when it actually helps his opponent.
 * Also using Gust of Wind to cheaply knock out your cards, which is usually a waste and just gives you a free switch (although occasionally this is the correct play with Gust of Wind, it usually isn't), rather than us
 * They also seem to completely disregard your ability to damage their bench pokemon cards, or the possibility that their resistance to your cards might actually help you (which, if you can damage their bench pokemon cards, can happen a lot).
 * There is other dumb stuff too which is difficult to know why it even comes up with such things, as damage swapping to one of their bench pokemon cards the same as their active one and then retreating to that damaged benched one, and then doing the same on the next turn...what???
