Garry's Mod is a 2006 sandbox game developed by Facepunch Studios and published by Valve. The base game mode of Garry's Mod has no set objectives and provides the player with a world in which to freely manipulate objects.
although gmod is older than me the game still holds up today. Youtubers make lots of videos on it, servers are still popular, and people are playing the game. Because its so old, the server system is very outdated and can make playing multiplayer very limiting. You can also mod the game and add almost anything, your imagination is the limit. 4.5/5
