I'm a huge Nintendo fan and I don't think I would have gotten a Wii U if I hadn't gotten it as a surprise birthday present. I remember when I launched shortly after I moved to a new apartment and didn't even know it was coming out until I walked into a Best Buy and saw the demo kiosk for it.
I remember when it came out and there was nothing I wanted play until Pikmin 3 (which I still have only played about half of). And after that there was only 3D World (which I didn't like as much as 3D Land), Captain Toad (probably my favorite original Wii U game), and Bayonetta 2 (which I own, but still haven't played, haha).
Other than those games, everything else that I was even moderately interested in were just ports (Zelda WW, TP), ended up being disappointments (Star Fox), or I wanted to play on other consoles like Rayman Legends (Vita), and all the ones coming to switch with improvements (Mario Kart, LEGO City Undercover, Smash Bros, and probably Mario Maker eventually).
Definitely the Nintendo system I've put the least amount of time with. But I do want to get back to Pikmin 3, finish Twilight Princess, and finally play Bayonetta 1+2. I didn't even buy Paper Mario for it feels like a game that might get a quick Switch port someday.
