1. that didn't seem to matter that muchAre we all forgetting that KH1 Sora is at half power after separating from Roxas? KH2 Sora could win with one hand.
Also, KH2 Sora can run up firetrucking buildings. Epic win
2. sora1 have his soul in most of the game, sora2 regain it in the end and I never noticed a difference.
