Wario needs a some new games: 1. a new WarioWare game that's essentially WarioWare Ultimate: it has everything from all the other games, but it's on the Switch and can be played on one screen for multiplayer action. The stuff that takes up an entire screen can be limited to either the local wireless multiplayer or some other creative solution.
2. An actual new game starring the man as his OG platformer self and not King of the Minigames!
