S&box is technically Garry's Mod 2 but in Unreal Engine 4. Hype and sad in the same time. Gamemodes would be hard to make and will need more knowledge on coding with new engine. We'll have to wait for workshop add-ons until it's as big as Garry's Mod current workshop. Though if S&box can be like GMod then I'll be hoping for it like all the Gamemodes and Add-ons all that crap. Cuz vanilla is boring lmfao.
