I've never played the PS2 version but to be fair the GBA one was alright. Story was dull, you basically revisit almost every world in KH1, it was linear, and i hated that dumb card system.

Its like nothing ever happened once the game ended, only the player and some characters know what all went down in Castle Oblivion. I can't talk about this game without treating it like the black sheep of the series haha.

To be fair it was impressive how they used animated cutscenes like the other KH games.
