Ever since it was announced, s&box has been carefully described by Facepunch studios as a "spiritual successor" to Garry's mod (Gmod), but not an actual sequel to Gmod. "S&box isn’t Garry’s Mod 2," says the studio. "It’s built to eclipse what was possible before—not just modernise it."
The link can be a bit confusing. Gmod was created by Garry Newman, the founder of Facepunch Studios, and uses Half-Life 2's assets to create a (drumroll please) sandbox environment, within which players can create games and scenarios. S&box has some of the same ideas but is its own game engine and creation platform, with much greater potential for users than Gmod.
