I think it would have been nifty if you could “create a rookie” for the PC, XBOX 360 and PS3 versions. Kind of like the character creation from games like EverQuest 2 or Vanguard: Saga of Heroes. Though I can see the technical trouble with trying to develop a good enough likeness for the CGI scenes for every possible creation combination.
So really it does make alot more sense to do it exclusively on the Wii as a reward.
