Golden Sun, F-Zero and Mother would be my top choices.
Here's more I like to see:
- Wario Land
- Pilotwings
- Waverace
- Excitebike
- Mario Strikers
- Mario Baseball
- Mario and Luigi
- Kid Icarus
Also sequels to some of the Wii U ports on Switch would be awesome like Pikmin 4 and a new Captain Toad.
