I'm not sure for other peoples uses but for me it saves me giving microsoft 20/month of my dedi server bill, for the other end then this can be done on a vps costing $5/month vps could handle 60+ players and also host a webserver for you reducing costs even more, basically its the ultimate way to do it on the cheap at small or big scales. example nitrous charge 10/month for 32player server i can get a vps for 5 that will handle 80-126 players depending on gamemode and addons and their functions/calls ect. Gmod servers run astonishingly well on low end systems and only for 1 thread
