Wow... I thought most people here hated that game other than me...
I really liked Baten Kaitos and I actually beat it. I usually don't beat my games because they get boring, but the battle system was awesome.
BK:O's battle system was really different, but I liked how much faster it was and the voice acting was like fifty times better than the first one.
I do like BK:O more than BK, but I still need to beat it.
