Well that would be wonderful Sega, although I'm not sure if it would work out for ya. Madworld did better than expected because it was unique while The Conduit didn't for the opposite reasons. But I'd rather not have anyone sellout just to make a game that will sell well.
But I'd love another Skies of Arcadia, Sonic Adventure 3, House of the Dead: Overkill 2, Madworld 2 (although not your property so could be difficult), etc.
