So here's my Wii/WiiU haul since buying the system earlier this week, all physical copies. Keep in mind I am totally new to everything Wii and WiiU.
WiiU: Super Mario 3D World, Mario Kart 8, Nintendo Land, Bayonetta 2+1, Wii Fit U (w/balance board & meter)
Wii: Super Mario Galaxy, Metroid Prime Trilogy, Sin & Punishment SS, Madworld, Rayman Raving Rabbits, Just Dance 1, 2 & 3 (wife loves them)
Tried ZombiU and didn't care for it. Enjoyed the Pikmin 3 demo and plan to pick that up eventually. Also plan to pickup Mario Galaxy 2, and the MK8 DLC.
Not a SSB fan, so don't think I'll get the new one. And I played (and still own) Zelda Wind Waker on Gamecube, so not too keen on buying the HD remake. Not sure about the various 2D platformers like Mario and Luigi U, Donkey Kong TF etc. Really have more games than time to play right now anyway.
What else should I consider for WiiU or Wii?
