I've actually thought about this before, never brought it up though.
I really think this would be a neat idea.
ZFGC's own personal game servers, for multiplayer games such as Team Fortress 2, Counter-Strike, Garry's Mod, etc. either hosted on someones computer (though they'd need a powerful server computer) or perhaps purchase a few games servers.
I know I'd use them and so would other I'm sure.
What do you all think? We could host tournaments and other events on them too.
