Omitting DK tropical Freeze and SM3D?...yeah...troll bait...
You're comparing games with completely different art styles, mario is not meant to look realistic, its meant to be cartoony and simple. uncharted 3 is meant to look as realistic as possible, same for forza. The wii u doesn't really have any realistic styled games for you to compare, maybe mass effect 3 and zombie U.
2D looks worse than 3D game.
If we take art styles, then you blind or what? Those games all look cartoony and simple. Also, realistic takes more power than cartoon.
Or Wii U:
Oh and that first pic is of Bayonetta (Xbox 360), not Bayonetta 2. (Wii U)
Sorry about then. Nintendo website game me wrong picture of game then.
I add other Bayonetta picture then.
