Hmm...
Animal Crossing: Amiibo Festival (not exactly great, but you should be able to get this brand new on a fire sale clearance somewhere)
Donkey Kong Country: Tropical Freeze (should be about as cheap as it'll get right now)
Lego City Undercover (there are ports out there now, I'm sure somebody is flipping this cheap. It was worth $100 for a short while)
Shovel Knight (shouldn't be expensive if you can find it)
Super Mario 3D World (should be about as cheap as it'll get right now)
Lego got a reprint so it's not worth what it was. I grabbed mine before that.
I have 2 sealed copies I bought on clearance before it shot up in value. I was kinda meaning to maybe sell one, but I never sell anything, so I'm kinda kicking myself now.
Is Shovel Knight best on WiiU? I couldn't find it when it was on clearance.
Smile Support Society. We play horror/retro games: Until Dawn Fatal Frame (Blind ghost killing us a bunch of times) Fatal Frame: Maiden of Black Water and Obscure: The Aftermath
I think the Wii U is where it was first released digitally, so that's why the Wii U version is highly regarded. But AFAIK every port was competent, so just buying a random one is fine.
So in today's Nintendo Direct, Xenoblade Chronicles 2 gets a Special Edition. Can't find it listed on Amazon yet.
