I got the Wii U maybe 6 months ago. These are my games so far:

Tekken Tag Tournament 2 (limited play)
Darksiders 2 (limited play)
Batman Arkham City (no play)
Injustice (extensive play)
Hyrule Warriors (limited play)

Mario Kart 8 (extensive play)
Zelda WW HD (free game from MK8 promotion, limited play)
Trine 2 (limited play)

So far I really enjoyed some of the games. I am still looking for a good racing game which is not open world in the city. Like the old ridge racers. Dont know if Most Wanted would be good or to wait for Project Cars.

I bought my Wii U around April this year, I currently have:
Super Smash Bros. (Physical)
Super Mario World (VC)
Zelda II (VC)
Wii Party U (Digital, Mario Kart 8 Promo)
+ MK8 DLC
