Engine problems and short dev time as well right?

Engine problems is putting it lightly, but yeah.
You can open up Freeside, the Strip and another area with mods and the already unstable NV struggles with it, even more so if you add more NPCs.

Even FO4 had some interesting plot lines cut, hell Cait almost had an engaging setup.
