The difference here is exactly what Xeno has said.
Back when I was here, if we wanted a server we posted "Lets get a gungame server" or "Lets get a BC2 server"
Right now, Sleggie has put the time and effort in trying to get a server for build.
Yes, as of now, we all kinda think it wont work because its RP, But its on Gmod and the gametype is fun.
He has the code, we got the dedi. How many servers are dead right now in SG?
So what is the harm in letting him get this server for a 1-2 week trial.
Who knows people might join and enjoy it and check out our other servers.
Its not like anyone else is doing what he is doing.
