I actually don't play garry's mod that much anymore, When I'm playing it I'm normally coding Lua or just messing about with Leaks really - I think the game its self wont die for a while but I'm more hyped for S&Box then actual Garry's Mod at this point, Maybe if Garry's Mod got a new engine and went straight to 64 bit I'd play it but this is un-likely
