Favorite games and accessories for the switch?

So far I have a Switch, Mario Kart, Mario Party (coming from EBay because cheaper price and 8% Ebay bucks), the Mario + Rabbids game, and Disgaea 5

I also put a screen protector on right after I unboxed it and just got one of those Case Kits at Walmart (with the padded case, game cartridge holders, etc), I know I wanna get another pair of joy cons, but what other accessories should I get and what are your favorite games?

Im having fun with diablo 3 and the sega genasis colection, though I have about 30 - 40 switch games, so thers alot to choose from. There should be a switch friend adding thread.
