I would like for all of the currently known Keyblade wielders to be playable at some point. Have a battle system like FFX had; where you can change your party members during battle.
I didn't buy one at first because it was expensive and there were no good games on it. Then when XIII and later XIII-2 came out I reconsidered buying a PS3, but changed my mind. I have to buy one now, for KH:ReMIX. NO EXCEPTIONS.
I hate the stupid card thing from CoM/Re:CoM, but I can over look that because coded/Re:coded had the weakest story in the series by far. Even Days had me invested to a small degree. I only finished Re:coded for completion's sake, but that game was firetrucking boring. >
Since continuity is a big deal for me, I am absolutely happy that Josh is still voiced by Aaron Spann. He sounds the same as he did in TWEWY, it's just that the sound quality of the DS isn't as great as the 3DS.
I love the all the interviews with Yasue! "KH on steroids", lol!
Also, I was really excited when I saw that scene of Neku and Sora until I realized that they weren't going to speak. NEKU, Y U NO SPEAK MAH LANGUAGE?
