Persona 2: Innocent Sin is awesome. It is tied with Persona 3 for me as my favorite game. It has an amazing and crazy story (that may get complicated) and extremely likable characters. The gameplay isn't the best, but it is not horrible. You can play Innocent Sin by itself, it is just that the ending of it is disappointing if you don't play Eternal Punishment. Overall, I still say it is a remarkable game, even if you are playing this standalone title.
