I just recently re-acquired KH2 and played quite a bit of it over the past few days - I was a little too harsh on it before, I think. All I needed to to was take a KH break
I still won't concede the fact that the original is the better game. It's a good game, though.
Chain of Memories on the GBA was a great game and I'm looking forward to playing through it in the PS2 KH engine.
