Agreed, though I like the game. It seems that many people miss out on a large portion of the story due to their neglection of Kingdom Hearts: Chain of Memories.
Oh, and perhaps the game is being remade for the PS2 since it sucked so bad for the GBA. It's so incredibly unworthy that it forces SE to make it again for a different console. =P
I don't think that's the case. I'm just exploring possibilities.
