When I first played SS13, the first server I ever played was CM, And when compared to other servers, CM is extremely simple, and without any knowledge of this game whatsoever, it took me around 2-3 days to get the basic mechanics of the game down. Everyone knows that rounds can average around 1-3 hours, so basically the devs expect people to know how to play the game in one round and it's dumb, stop doing it please
