^ This is a plentiful, bountiful, and solid land valley just past the mountain barrier west of goodsprings. With so much bountiful land that is still technically in the boundary of the map according to the pipboy: why is it not used to build massive open world cities? Why let so much land go to waste? Even if you run out of land, which is pretty unlikely, you can build over an infinite yet irradiated ocean, just paving over it would suffice.
There is so much boundless potential: why don't modders use this land to their advantage? There's sooo much land just ripe for the plundering. I've not seen a single expansion mod use the boundless areas of the map, and that's a shame as I see so much potential in them.
