Sandbox Game: Garry's Mod

[vix4723]

Please add Garry's Mod to the list of Sandbox Games.

There are a few sandbox games and adding Garry's Mod could be a great addition :)

WAT?? It's open source now?

Part of the source (Lua, configuration, etc.) is up on GitHub: https://github.com/Facepunch/garrysmod That doesn't count as open source though, as there is no license.
