Not Warren Spector! Where does he go from here?
Honestly, wherever he wants. He's Warren fucking Spector. He should join Ken Levine at Irrational and get to work on a new Thief.
Yeah, pretty much this. Spector has credits in some of the most loved games* of all time so it's a bit confusing that he sunk so much effort into this Epic Mickey stuff.
*Ultima Underworld, System Shock, Deus Ex, Thief.
He's a huge Disney fan so it's not really confusing at all.
