Nippon Ichi/YMMV


 * Nightmare Fuel: Quite a few things, many of which are probably compounded by the cute 2D-sprite graphics.
 * Cliché Storm: In full force concerning Gust, IF, and Hitmaker games.
 * Crosses the Line Twice: Every. Single. Game. Soul Nomad and the Disgaea series take the cake.
 * Game Breaker: All their Turn Based Strategy games actively encourage munchkinism, intentionally letting you power up weapons and characters enough to One-Hit Kill anything in the game.
