I'm a pretty big Kingdom Hearts fan. I have KH2 and chain of memories, and I'm borrowing the first one. Also I'm going to get Birth by Sleep and 358/2 days. Yeah I've played them a lot. If you want to know, here's my progress:
Kingdom Hearts 1: level 70 something. Still working on Ice Titan, Phantom, the guy in Agrabah, and Sephiroth.
Chain of Memories: Sora is lvl 99 and I beat his story. Riku is level 30 some and I beat his story.
Kingdom Hearts 2: Level 99, lvl 7 in all forms, beat everything except hades paradox cup.
