Darksiders 2 is far from a perfect game but neither was it's predecessor. I actually think the Wii U with touchscreen integration & exclusive dlc inclusion made the Wii U version the one to pick up.(I was debating between the 360 and Wii U version).
NintendoLand (had a blast with my wife and kids all the time) 8.5
Trine 2: (better gfx, more levels than PS360, touchscreen) 9.0
Darksiders: (see above) 8.0
NanoAssault: (nice visuals, tight controls, too short) 8.0
New Super Mario bros Wii U (a more polished version of NSMB:Wii in HD) 8.0
Scriblenauts Unlimited:(more stuff than 3DS, HD visuals) 7.8
NinjaGaiden(Better Visuals and more polish than the original PS360 version) 7.5
Assasin's Creed (on par visuals with PS360, nice genre for WiiU) 7.0
ZombieU (Decent graphics, unique gameplay that I appreciate) 7.4
Need For Speed (I hate the controls the visuals and gamepad integration are nice) 7.5
The Cave ~6.0
Tank Tank Tank!!! ~6.5
Mighty Switch Force! (got it on sale...it's the same as the 3DS version only in HD)~ 6.9
that's it for now.
