Playing the Kingdom Hearts games in "chronological" order, I played KHII before BBS. While I can recognize KHII is the better and more ambitious game, this has become my favorite Kingdom Hearts game I've played. The Command Deck feels like what Re:CoM could've been if it hadn't sucked, and leveling and melding commands was extremely satisfying. The gameplay wasn't as good as KHII, but the transition from Terra > Ventus > Aqua really felt like a developer-intended progression of the Command system, and by the time the Final Episode rolled around I felt fully in control of the gameplay systems and it just felt GOOD. I love that each playthrough of the three main characters felt almost completely different, even though they visited the same worlds. The story was great, and it was really interesting to see a "prequel" of sorts in the character storylines as well as the Disney worlds (anyone else notice it was more heavily geared towards the early Disney movies?). I had a blast playing this one, and it's one I wouldn't mind revisiting.

Oh, and Leonard Nimoy absolutely killed it as Xehanort.
