This is my favorite technical writeup. I think I asked you before on here if you still had info about how PA's pathfinding or csg geometry worked, those were two other cool things I remember from the OG tech demo.
I don't know anything about the CSG. I didn't start the pathfinding system,m but I did a lot of work on it. I could maybe someday turn that into a blog post. But I don't have source access anymore.
The tldr of pathfinding is voxels and flow fields.
