I have a large library of steam games, but yet always come back to Garry mod and ravensfield. I keep coming back for the modded content and every other game is excellent, don’t get me wrong. But a lot of big games like RD2 and watchdogs 2 just seem like such a long time investment. What 2 games do you infinitely come back to?
Assetto Corsa (assuming mods are included) and Factorio (again, with mods, but to a lesser degree).
