I really struggle to wrap my head around how this engine works. I haven’t used it, but I have experience with Source 1 and its systems and I imagine Source 2 is an extrapolation of that. But I really can’t wrap my head around how they’ve turned it into a scene-based game engine when Source 2 is map-based, how they’ve managed to build a completely different editor that still leverages Hammer maps somehow, and all the other stuff.

I've never tried s&box but Source 2 did overhaul the map and asset pipeline quite a bit, everything's a plain mesh instead of BSP and maps are also regular .dmx files, so I'd imagine it's slightly easier to build tools that work on top of it

It is a heavily modified Source 2.
