Garry's mod 1 or 2 ?

Garry's mod 2 is not Garry's Mod 2 but will act the same way as GMod does but its a actual game they are making not a mod and its called Sandbox/S&box and you can see the development on it through their website. But for right now we don't know 100% what S&box will do 100% but i do hop their is better to code for than lua big on server development so im excited. Also they are keeping some of the same game-modes from GMod so that will be cool to see as well. They where using the Unity Engine then Unreal engine now they moved to Source Engine which is sad but hey that is what the development team is use too. But right now its 50/50 on my answer until i see S&box in action .
