We just got a switch and started out only with the Online Sub + Expansion and really like it. Classic games are really fun. Especially SNES games. N64 games feel a bit rough to play given it was the early days of 3D nintendo. My only other complaint is the bunch-of-games-in-one games (like a SNES Kirby collection), it's not very intuitive how to switch between games.

But goodness, Super Mario World & Donkey Kong Country, Yoshii, etc. Great stuff!
