“We wanted to do an Alice in Wonderland part of Wasteland and, as the story developed and as I looked around at my team and saw what they were excited about, I didn’t have anybody who was gonna champion that land, who had great ideas for adventures in that land... Someday maybe we’ll come back to it; maybe someone will come along and say, ‘I’ve got an idea for the story in Wonderland’ and we’ll talk about that and maybe it shows up in a game someday." - Warren Spector

Spector also discussed the musical elements of Epic Mickey 2. He says that if things go well this time, he's going all-out with the mechanic in a future title.

“I always knew that the second game was gonna be two-player co-op and that Oswald was gonna be a playable character. I knew that in 2005. That was a done deal. I had some really crazy ideas about ways to use music in games, that seemed very Disney-like to me, and you asked about how do you cut things? Well, you can’t do everything so that didn’t make it into the first game, which was fine. And I know where I’m going with it, someday, I hope, maybe, but this time around, in the second game, I just wanted to take a baby-step to making the full-blown interactive musical game. This is not it. Gamers, you tell ’em there are songs in the game and they start getting panicked, but I just want to see if people will accept songs in games and, if they do, next time I’m going crazy. People don’t even know what’s gonna hit ’em.”
