Pokémon Conquest/YMMV

And the Fandom Rejoiced: The mere announcement of such a unlikely crossover game between one behemoth of a franchise and one mostly obscure/unknown-outside-of-Japan franchise.
- When it was announced that the game was getting localized in other countries, successfully averting what many fans thought would be a likely case of No Export for You.
  - No Export for You being averted in America doesn't mean it will be in Europe, especially considering how many great RPGs/Tactical RPGs never see the light of day there, so not all of the fandom rejoiced yet.
Anticlimax Boss: The first fight with Nobunaga. It's probably intentional, though.
- The Zekrom that Nobunaga uses. You hear its roar on the title screen, it accompanies the Big Bad throughout the main campaign, and much is made of the battle leading up to fighting it. Ultimately, it's not much more difficult an opponent than any other in the game, and its Warlord even replaces it in a subsequent fight!
Anti-Villain: Pretty much everyone you end up fighting. Makes you think whoever started that legend was kind of a dick. See Fridge Horror below.
Crowning Music of Awesome: The game's theme song, for starters.
- The game also gave us some pretty good battlefield themes. For example, here's the Flying, Fighting, Electric, and Poison Psychic and Normal battlefield themes.
Crutch Character: In the main story, Shingen might qualify. His Rhyperior will probably be the first fully-evolved Pokémon you get, and at the point you do its Rock Wrecker one-shots nearly everything and it's a virtually indestructable tank, to boot. Later on though, when the other Warlords have evolved their Pokémon, you'll find others are able to do just as much damage for far less cost. And at that point Rock Wrecker's low accuracy really starts to show.
Demonic Spiders: Anything with Dragon Rage if encountered while your Pokémon's levels are still low. Which, unlike in the main games, is actually quite likely during some of the extra chapters (Ieyasu, Mitsuhide, and Nouhime all have a pretty big problem with this seeing as they start right next to the Dragon Nation).
- On the flip side, this makes Ranmaru (with his Dratini) a Disk One Nuke if you manage to recruit him early.
Disk One Nuke: Only applies to the extra chapters. Despite Links being reset, Bag of Spilling is averted for the Warlords as far as Pokémon are concerned - meaning that if you evolved their Pokémon in the main story, they'll be evolved here. Despite their Links being reset, though, they should still roll over any early-game opponent on account of them still being stuck with unevolved Pokémon.
Fridge Horror: The legend. Sounds like a basic Gotta Catch Em All plot, but remember these are actual nations we're talking about - which are presumably populated by hundreds of people. How would you like it if your country was invaded on a daily basis just because everyone wants a shot at the Legendary Pokémon? To be fair, Oichi notes this in-universe.
Goddamned Bats: Yes, Zubat are in this game, but they're not this trope due to only having one (fairly standard) move. Surprisingly, the trope is evoked not by Zubats, but by Sewaddle - specifically because Bug Bite devours ANY consumable item in this game, not just Berries. Say goodbye to all those Potions you just bought! You see a LOT of them early-game too.
Magnificent Bastard: Nobunaga, of course.
Ms. Fanservice: Nene, Nouhime (though she actually covers up more in her upgraded outfit), Kunoichi (her upgraded outfit is basically just her in Black Bra and Panties), Kaihime, and Inahime all probably qualify.
Padding: Some of the post-game episodes have you doing things like befriending 100 Pokémon as your only goal.
That One Boss: Mitsuhide in the main story. Mostly due to the annoying Frictionless Ice you have to cross, which pretty much works like the Ice Path in Pokémon Gold and Silver except you can only move once per turn, and it makes getting into range of your attacks really difficult. Flying Pokémon can ignore the ice, but guess what they're weak to, and what every enemy uses... Oh, and one of the generic enemy warlords has a Munna with a nasty habit of putting all your Pokémon to sleep. The Munna is also levitating, so it ignores the ice. To top it all off, Mitsuhide himself is no slouch; his Lapras is decently bulky and is equipped with the Awesome Yet Practical Ice Beam (an attack that hits everything in a three-square line, has near-perfect accuracy, and is adequately powerful, to boot).
That One Level: Mitsuhide's post-game episode. You start off surrounded by Nobunaga's forces, and he controls so much territory he'll always have enough room to retreat his Warlords to another province when you defeat them. Which means recruiting enemies is next to impossible, so you're forced to take on the entire chapter with just Mitsuhide, Gracia and generics. Oh, and I hope you got Gracia a Gothita in an earlier chapter, because her default Pokemon is incapable of inflicting actual damage! There's also the very real possibility of Nobunaga himself moving to a nation adjacent to one of yours, whenever he feels like it. Oh, did I mention it's also a Timed Mission??
What Do You Mean It Wasn't Made on Drugs?: A game series set in one of the bloodiest eras in Japan's history... blended with a kid-oriented franchise?
