Hyper Light Drifter, League of Legends, Overwatch, Starbound, Cubeworld
Hyper Light Drifter is a beautiful game with a beautiful soundtrack and great story and enough content to keep you going for a while
League of Legends is something you can get better at, and regardless of all the terrible and angry people on it, it's still pretty nice to work together with a team like that
Overwatch is like League but with less/more easily ignored toxicity. I don't really play shooters but I'm getting better
Starbound I like a lot. I dunno why, it's just nice. Space, building, aliens, exploring, mining, whatever.
Cubeworld is really pretty and really simple and great for exploring casually, but also for relatively challenging boss fights with the option of multiplayer.
