Aka Wii U exclusives. The console Nintendo wants us to forget. The Switch has basically become a second home for the more popular Wii U titles, but still some remain unplayable on anything except Wii U. Many of these are likely to never be re-released due to them being obsoleted by other games, like Mario Maker, Splatoon or Smash 4, or having their time passed (the Mario & Sonic Olympic games).

If I've missed anything let me know. There are a couple of games here that were released on 3DS too, but are different enough that they warrant being considered their own games.
