WiiU is the worst console I ever owned by far, and I loved the Wii. It's unbelievable how many things Nintendo did wrong with that horrible excuse of a console. In fact, they didn't do even one single thing right!
I agree with everything but the "1st party being lackluster." Mario 3D World, DK:TF, WWHD, TP:HD, Pikmin 3, Mario Kart 8, Smash, Splatoon and a few others were really good. Some just flat out great. Everything else about the Wii U sucked.
I enjoyed Color Splash as well. Captain Toad was fun. Bayo 2 was just amazing. Though I suppose that was second party.
