Isn't Garry's Mod just Garry's Mod 10 anyways? I remember something about there being Garry's mod 9 as an older version.
I don't think there is anything wrong with making bigger better newer games, nobody keeps people from playing the old game.
But a new game once in a while is some fresh air.
Nobody plays anything cool in Garrys Mod anymore, only the same few Mods have a populated Server, the small, innovative and interesting stuff all died out.
Same with Warcraft 3 and the likes.
I would appreciate a Minecraft 2.
