Will Facepunch release Source2 source code after S&Box release or we will only be able to make SURE&Box adding, not Source2 games based on S&Box code?
This is up to Valve, they promised Source 2 a while ago so maybe they plan on making it public a the same time as S&box comes out.
Facepunch doesn’t have a permission to release the engine code licensed for developing games using it. If Source 2 ever gets open source, it’s Valve but not Facepunch who releases it.
Having said that, I hope Valve takes facepunch work on the C# layer and ship it with it. It’s much more accessible than C++. And more flexible than lua.
