Gmod is dying but when ?

It will take a long time, but probably you might see a mass decrease in players when S&BOX comes out.
I swear to god that thing looks easier to make content for, just can't wait for it to come out.

The game most likely still has atleast 5 years of decent playerbase time til its probably gonna swiftly die of especially if theres a better optimized gmod like game to replace it

A really nice and new way to have users download files! Hope this works

Garrysmod is timeless. The only thing that would probably beat it is some sort of GMOD on source 2.

Won't die until s&box will finally release hopefully

I don't think GMod will ever completely die, it will just be hanging by a thread. Only when a good alternative comes around will Gmod almost die.
