The "permanent changes" thing seems to only be related to the world, so I wonder if that will actually affect the story at all.
Having said that, thank goodness. I hated coming back to a place and everything being reset.
The concept of not having to defeat anything is pretty cool (though not exactly new or anything). I *really* want an option to switch to Oswald (and have Mickey follow you), so I hope that, if not in this game, a 3rd game does that.
As for story, I loved Epic Mickey's. When I saw the end of the original, I got kinda sad and that "feel good" thing at the very end, but oh man, I was so sad it was over, so I am glad I get to go back with a new story and I can't wait to see where it goes.@Darth Vader
No game's ever gotten to you emotionally?
