Also important: That space is very close to the Player 1 start.
That's an important point, too. Also, it has a very high ceiling, and another ceiling is like a "border" around it and a bit lower, so I can test ceiling spawner efficiently in this area. Also, it's useful to set up a few command line parameters and some development key binds ("NoClip", "Fly", "SV_InfiniteAmmo 1", "Freeze", "Resurrect", "Give All"), which makes testing there even easier

It's like the ultimate testing map!
