Well, as CliffyB just said that the platform market is "DEAD" in IRC, could this be a 3d Jazz FPS?

Before you start bashing your head into random objects, think about how cool this could be. Picture all of that Unreal-type polish in the Jazz universe. Think of a cross between Unreal and Sonic but with the Jazz cartoony style (although I do think cell shading would look like crap for this kind of game). Crazy jumps, walljumps, coptering, running around in a 3d environment. Then picture something like the UT2003 adrenaline system for special moves. Think about what the mayhem of multiplayer could be like. This could be seriously dope.
