Best Switch games?

I'm looking for some good games (downloadable, too lazy to go buy the actual game 😂) that both me and my 9 year old could play! He's been on a HUGE fortnite binge lately and I want to find something to switch it up a bit.

We already have: Breath of the Wild, Fortnite (I won't play it lol), Evoland 1&2, Paladins, and he downloaded Brawlhalla not too long ago.

I considered Stardew Valley because I already have it on PC, but i get into binges of it and then don't touch it again for ages. Lol I also thought about getting one of the Pokemon games more for him than myself, but i played the demo of Lets Go Evee and i don't think he'd stay interested long and i don't want to spend the money for him to lose interest after a day. Lol

I also will be purchasing Animal Crossing upon release, but again don't think he will have much interest (it's for myself 😂)

Any suggestions? What are your favorites?
