The creative director and the lead designer on Assassin’s Creed III have both recently publicized the WiiU version will be the same as other platforms.
Alex Hutchinson the creative director kicked off the comments by mentioning that at Gamescom the team was happy to prove “that all consoles for once are the same. Between PC, 360, PS3 and Wii U, they’re the same game.”
Steven Masters the lead designer soon backed up these comments by revealing “It’s the same assets and the same engine.” Adding that, “the guys in Quebec have been porting it for quite a long time.”
So if you were thinking off picking up a WiiU you won’t have to worry about a second rate Assassin’s Creed title.
