I've played Kindom Hearts 1, 2, 358/2 days, Dream Drop Distance and Chain of Memories (GBA)
They're OK in my opinion. But it really does say a lot that Chain Of Memories is by far my favourite KH. That and Dream Drop Distance are the only ones I would say I "like". It keeps drawing me back. Curse my Disney filled childhood!
TWEWY I remember having a bloody confusing combat system. But so many people like it, I feel like I owe it a second chance.
Final Fantasy 8 is next on my list, when I'm in the mood. You see, my first Final Fantasy was 1 & 2 on GBA. I've played every single one up to 7 for the first time in order, so I'm keeping it like that. (Except for 11, because online, you know?)
