I don't know why people hate it. The story was actually, imo, one of the least cliched in the series. The battle gameplay was ok, but the controls were pretty bad imo. The characters are probably my favorite part of the game, much better than symphonia, destiny's, and some characters in abyss imo. It isn't the best one, but it is definitely not the worse. I don't know if people actually hate innocence or some are getting confused with tempest(which is sometimes thought of as the worse in the series, but it wasn't a mother title so I don't really care to much). The fan translation for innocence should be done soon for anybody who wants to play it and has a flash card. I might replay it when the translation comes out just to see how much I understood and compare it.
Is anyone going to translate Tales of Hearts? I would love to play that game.
