Oh boy so much to say about the wii u. Before it I could have been considered a "casual gamer" because I wasn't heavily involved in the gaming industry (and by involved I mean I didn't have too much knowledge), to the point where I never really thought why some games like fifa didn't come to the wii u, I just said "well those aren't nintendo games".
As time progressed I started joining sites like vgchartz to find other people to play and all that good stuff, but as I joined more sites my curiosity and knowledge increased and just like that my involvement in the gaming industry went beyond just playing games.
Unfortunately all that involvement just made me enjoy my wii u less and less as time went by because I started to see flaws that as a "casual" gamer I never even think of, however at the end of the day I still loved the time I had with my wii u because thanks to it I was able to meet some great people.
Some of the games I love:
Smash 4
Mario Kart 8
Monster Hunter 3 Ultimate
Bayonetta 1 and 2
Pokken
Splatoon
Wind Waker HD
Mario Maker
Batman Arkham City
Lego City Undercovered
