Perhaps it's just me, but I'd have preferred one "Final Fantasy" world, as opposed to all the FF characters adopting Hollow Bastion.
I'll admit, I was drawn in by the "SQUARESOFT" tag on the front, and nothing else. After playing though, I'm glad I was. The battle style makes for a refreshing change from FF's turn-based system. Though I marked out mildly throughout the game, they were nothing compared to the appearance of the Chernabog, with an accompanying mix of "Night On Bald Mountain".
Played CoM, but only to get the story. I played it on an emulator with all the cheats I could find. The style of game didn't really feel right to me, so I was far less interested in it. If it didn't have some of the story in it, I wouldn't have played it at all...
With KH2, Axel could do no wrong in my eyes. I also loved every minute of Pirate World.
