Cheaper smaller games:
(on sale you might grab them for a dollar)
Akane (singleplayer, arcade like)
Astro Bears (multiplayer, like tron in 3d against each other)
astro duel (multiplayer, like astroid as battleroyale. supports more than 4 players!)
______________________________
more than 30 dollar games:
I like the monster hunter game on switch, but the playerbase was kind of dead since the release.
If you have friends to play it with, this is a good game
it has insanely much content
mario maker 2 is good for singleplayer if you like jump n runs. but dont play it for the multiplayer-> the shared camera for multible local players makes it unplayable, it's really bad implemented. and online is a bad joke.
