@ReggieNator: I was thinking about that, too--I think a decent solution would be to have you 'look' toward the side of the screen to turn the game world. Metroid and Medal of Honour have 'dead zones' that you point inside of to aim the gun, or point outside of to turn, and it works really well. I think that could translate pretty nicely to 'looking' in a head-tracking game.
@the idea of multiplayer: sure, they could do it with splitscreen. You'd just need two-four pairs of headgear and a lot of space 
@Topic: When they pulled the feature from Boom Blox, didn't they say it was because they had bigger and better ideas for it?
