first, there was great greed, for gameboy.... sortof.
See, i bought it thinking it was totally something else, only to find out it was a final fantasy legends sortof knockoff game based loosely on some anime i never heard of. All the characters/enemies are named after food objects with the exception of the anagonist "biohaz". the story was lackluster and the gameplay was monotonous. still, it had quite some charm to it, and i like playing it once in a while, despite my utter rage the first few weeks i had it.
Final fantasy x-2 and ultima runes of virtue both make my list of games i wish i hadn't bought.
i also hate whomever made diablo 3, its not even diablo.
edit: oh man, i forgot about the newest prince of persia game! the game is beautiful, and the plot isnt horrible, but the fact that you have no hp, and literally CAN NOT DIE, takes all of the f un away. you cant have a game with no punishment for failure.
