Well I didn't buy the game, but a friend of mine did and I saw quite a bit of the game in action. I'd have to say it's a bit of a mixed bag. I have the game on 360, and there were things that I liked better on Wii U and things that I prefer my 360 version for. The graphics, to me, weren't all that different. Implementing the gamepad is well done, and even having beat the game already it did add enough to make me want to play through it again. There were spots when the Wii U version had some texture issues. Being close up on certain buildings lacked detail that's present in the 360 version. As far as framerate, nothing really noticeable to me that ruined the experience. I haven't played through the entire game on Wii U but if you don't have it already for another system, then I say it is a fun experience. I don't know about $60 worth but you do atleast get the dlc right off the bat so that could warrant the price tag a bit more i guess.
I WANT MY NON-SPECIFIC ACTION GAME!!11!1
