quest is real cheap, anon. 

try 
Vox Machinae (mech riding game)
Compound (arcadey kind of retro-ish shooter)
Hellsplit Arena or Blade and Sorcery (hack n slashy first person arena games)
Gorilla Tag is literally free, (but pub lobbies are also full of children)

And a few anons here play Assetto Corsa
