So, let's suppose that after Wizard City has been fully revamped, Kingsisle keeps going and redoes the graphics of the other worlds. At what point would they stop? What world already has graphics good enough to not need updating? Or would the artists just keep improving until, by the time they improve Empyrea (or whatever world they're on at the time) they're good enough to start over on a second makeover to the whole game? Would they just get into a loop of sending endless waves of improvement down the world list?
