If anyone here is looking for some good roleplay experiences on Garry's mod, check out the Clockwork Servers ( they look like this: " CW : gamemode, or CW : Black Mesa " ).
In all honesty, most of these servers are still good, but many of them are Pay-2-Win, or have systems very similar to it. But don't mistaken a pay-2-win server for being a bad one. Trust me, any server can still be good, even if its pay-2-win.
