Get ready for a long list:

Trine 2
Nano Assault Neo
Puddle
Mighty Switch Force 1 and 2
EDGE
Toki Tori 1 and 2
How 2 Survive
Kung Fu Rabbit
Unepic
Knytt Underground
Little Inferno
Stick It To The Man
Child Of Light

Those are all of the ones I've bought and they're all worth every penny.

i shall print those out and check tehm out tonight... of course I am sold on earthbound on Thursday and I will keep hoping for a physical release of Nes remixes

I got earthbound last night!

I also recommend Squids Odyssey which is a cross buy game in Europe. Really fun game, and you get it on both Wii U and 3DS.

Note if you're planning to get it, buy it on 3DS first, you have to buy that one first to get the other version for Wii U for free.
