...would you play on it? It would be a roleplaying server.
Note that this would not replace either of the minecraft servers, and it would be hosted from a different location, so it would not be detrimental to the performance of the current server.
I would definitely play on a Gmod server. Maybe we could eventually expand to a TF2 and L4D2 server as well? Especially if we were to run the L4D mod that brings the max number of people on a team up. It'd be awesome playing games that require different skills with everyone.
