Here is some problems why the server is not popolated.
-For eu players the server does not show up when you search in the servers list even if you search for max ping 150. I have to have the ip and add it to favorites thats the only way i can find the server. I think css has the same porblem over the last year to.
-The nubs of cs:go want to have auto jump and they dont play if there is no auto jump on mods like MG. But i refuse to play autojump as do most of SG. But I would say that 50-70% of the players would not play MG without auto jump. This is the case in css to
-Some maps are buggy/broken maybe not the entire map but some levels on multigames maps i do not know if others servers have those maps too.
