If you still have a PS2 (You mentioned Kingdom Hearts 2), I'd suggest .Hack//G.U. I've been playing it for the past two weeks and there's a lot to do. The Book of 1000 is like Jiminy's Journal on steroids. The battle system can get a little stale, but that's to be expected in a game that's over 100 hours long. But there's motorcycle races, avatar battles, and other stuff to keep you entertained.
