Super Mario 3D World, Super Mario Maker, Mario Kart 8, Pikmin 3 and Super Smash Bros. for Wii U are undisputed, in my opinion. I've not played Affordable Space Adventures or Runbow so I wouldn't say, and I've not played enough of Splatoon, Bayonetta 2 or Wind Waker to make a fair judgement. The first Bayonetta and Rayman Legends are the only other two from your list that I'd say are open for debate.
In a week in which ASDA have been nationally selling PS4 bundles for £200, I've decided to pass on getting one for the time being. Truth be told, I don't exactly need to be spending any more time playing games than I already do. I can make do with what I have (which, admittedly, is much too much, and needing taken down to CEX). Besides, by the end of the year I'll expect to have AC Happy Home Designer, AC amiibo Festival, Mario Tennis Ultra Smash, Rodea The Sky Soldier and Chibi-Robo!. It's not vintage, but it's a line-up that should keep me occupied well enough.
