Current collection post trading my physical collection in (and some other nonsense) and going full digital. I want to prioritise picking up MHGU, Spyro trilogy (assuming the port's good), Astral Chain (assuming the game's good) and a bunch of indies (I want to know what people's essential indies are; I picked up the HM collection because I had a suspicion it would be pulled from the AU eShop and I was right).
I'm happy enough with 1P games (unless people are really insistent I pick something up based on what's listed here) and I can probably pick up other third parties like Mario + Rabbids later (same deal).
Hollow Knight would be my essential indie pick, if you haven't played it already.
If you're partial to Metroidvania and sci-fi, I would also recommend Axiom Verge.
If you like action-adventure, then Hyper Light Drifter as well.
The indie scene is incredible right now, and these sorts of games are perfect for Switch.
(I played Axiom Verge on Vita and Hyper Light Drifter on PS4, but may double-dip on Switch because they're so good.)
