Wii U exclusives

Nintendo Land (overpriced physical)
NES Remix
NES Remix 2
Pushmo World
Star Fox Guard (or buy Guard + Zero physical)
Affordable Space Adventures (apparently really good?)

If you want Dr. Luigi, don't. Dr Mario: Miracle Cure includes that mode and is cheaper on 3DS.

Apparently the Dillon series is good? But it's 3 games for 10+10+30 or so. Too expensive to try.

I didn't get any VC Pokemon GB games. Get them if you want to transfer up the HAs or rare moves.
