We all know Garry's Mod, the landmark physics sandbox mod for Valve's Source Engine that can be used for everything from creating custom game modes to messing around with Half-Life 2 characters ...

In our world, though, Garry's Mod won out, and JBMod is only just making its way to Steam now, 18 years later. "JBMod was the first mod ever released for Half-Life 2," developer Team JBMod explains.

Yet Garry Newman of Garry's mod has now achieved "Yes, I am the real Garry" and Steam popped the achievement. "Finally got this," says Newman, posting a screenshot of the achievement.

Garry's Mod has entered the Guiness World Records: Gamer's Edition 2025 as the best-selling PC exclusive of all-time.
