Just Cause 2.
Dont care what anyone else says, ignore them.
"Just"
"Cause"
"Two".
handicapped forcing ignored, I would reccommend Space Engineers aswell if your computer can handle it, and you're patient when it comes to updates. There isn't forgettons of content, but you certainly do tons if you take the time and got an idea in mind.
If you don't have it, Gmod would be above both of the games I just listed. Over 2700 hours on it on my end, almost endless fun depending on the gamemode.
Never a shortage in servers, either.
Either way, it's up to you more than anyone here.
