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?
Tough question. I’d say Stellaris and Neverwinter Nights.
Stellaris is giant with so many options, it would take a while to get stale.
Neverwinter Nights has hundreds of homebrew campaigns available, and with the PRC mod also hundreds of classes & races to play.
