You should keep an eye out for S&Box! It's the successor to the popular Garry's Mod. Garry's Mod is, imo, the sandbox and modding game and I think that S&Box will be even better. It's based on the Source 2 engine, and the main developer Garry has collected a lot of experience with GMod.

While GMod mods are based on Lua, S&Box uses C#, which is an awesome choice, imo. C# is a bit more verbose than Lua, but it probably enables mods of higher quality.

It's not out yet, but some keys get distributed to chosen people. Sadly, I'm not one of those.

Thanks, subscribed to their subreddit. Never had the time to jump into Garry's Mod but might give this one a try when it comes out.
