I’m planning on getting a Switch soon myself, and here are some games that I’m most excited about:
I guess those last 3 don’t quite fit your requirements, but the others are mostly platformers or narrative-heavy RPGs. I’m also gonna buy Celeste again, because it is the single best 2D platformer I’ve played in years (maybe to be beaten by Hollow Knight, or so I’ve heard).
The Switch is an awesome indie games platform, and for me, since I own a Mac and not a PC, there are actually quite a few interesting games like Viviette that I wouldn’t be able to play otherwise.
