While GMod does not possess any actual gameplay value in a traditional sense, it enables the player to freely manipulate all of the objects and features of the Source engine except for the background features. Valve also no longer categorizes Garry’s Mod as a modification, but rather as a full game, due to its ubiquity and popularity. Garry’s Mod no longer requires one, although it is still possible to mount a game to be able to use its content.

Do you need a Garry’s mod to play half life?
