Believe me it's not that great... I didn't even bother finishing Re: CoM, Re: Coded was better then Re: CoM. >.> Well.. In my opinion.
Both games are pretty horrible though...
I don't really care about the game personally... Yes it's the final mix version of KH1, but KH1 final mix had nothing special to it. I'm more excited for Kingdom Hearts 2 Final Mix HD and Birth By Sleep Final Mix HD. :P
