While offering immense creative freedom, Garry's Mod presents some social risks due to its user-generated content and competitive multiplayer modes, which can lead to competitive toxicity and social comparison. Although 'stranger chat' is noted as absent, interactions within game modes can still expose players to challenging social dynamics. Content risks include moderate levels of violence and potentially strong language, depending on the specific mods and player interactions. The game has minimal dopamine manipulation and monetization risks, as it lacks microtransactions, loot boxes, and manipulative engagement mechanics.
