While a regular 2k players is nothing to scoff at, compared to the 2013/14 version of MCSG, the server has taken a large turn for the worse.
In my opinion, the thing that killed MCSG is how there's no dedicated community anymore. What used to be an intricate network of clans, friends, and staff has turned into a mindless group of hackers and tryhards. What happened to all the community events? Hell Games? Clan wars is dead. Does Chad stream?
The server is still breathing, but unfortunately the glory days are long gone. No matter how many fancy map and website updates they put up, the underlying problems will eventually dismantle the server.
