Blade & Sorcery is nice, got mod support.
Pavlov is nice if you want to play VR CS, TTT or nazi zombies
Rec Room is a nice game with lots of mini-games, a lot of kids play it though so if you can't tolerate kids it's not for you
Onward if you want a infantry mil-sim

This was really not a list of what to buy first now when I look again but they're all decent games that you should give a try.
