That’s Joystiq’s term for it, not mine, although it isn’t exactly an inaccurate label:

I’m still digging the very classical styling of the game’s visual elements, especially the old-school Mickey Mouse look. Interestingly, the trailer suggests that Mickey’s dialogue (such as it is) is also a throwback to the earliest Disney cartoons featuring him; he doesn’t speak once during the trailer (he does this sort of squeak/grunt thing).

I think Warren Spector has a hit on his hands. I hope he does, at any rate.
