How can you leave out Metroid Prime Trilogy! The first installment is probably the first in a list of less than fives games that I've finished multiple times.
Sure, but Metroid Prime is a GC series that they haven't updated :-( To play it these days you're actually just better off playing it in Dolphin, which I recently did. It looks great you can even get texture packs to upgrade it.
True, I'm really hoping we'll get a new Metroid game on Switch. That said, for many people the control scheme of the original put them off, so being able to play it using the (easier) Wii controls, higher resolution, and getting the whole trilogy for about 20 bucks is a pretty nice plus of having a WiiU.
Unless you hate these types of backtracking games, of course :).
