Ha, no. What made Mass Effect good was the way you could transfer your save files across. As Mass Effect 1 and 2 are not on the Wii U that feature is not existent on the system. Besides, anyone who wants the game will likely already have it; look at the PS3 sales of Mass Effect 2 compared to the Xbox 360
Sales will be average at best. And for the record Mr Riccitiello, Batman: Arkham City is the best piece of software announced for the Wii U so far.
