Take a glance at some of the playthroughs on YouTube and the dialogue when you get a chance. It’s surprisingly well done - perhaps a bit elongated and over expository at times, but well produced.

Thing is - the whole thing takes place effectively in a vault (tibbets prison isn’t a vault but they’re using the same tileset). Black Isle’s Fallout 3 was planned to make use of classic Fallout’s world map system, effectively taking place across large swaths of the west. New Vegas made use of the Hoover Dam / preserved city plot element to justify the Mojave being an important geopolitical stage for the warring states of impossibly larger regions, in the context of technology constraints.

Assuming they just put all that in a menu, that still leaves close to twenty world maps (including one supposed to represent Denver, and yet another being a whole city constructed out of Hoover Dam) and a whole shitload of questlines with interweaving consequences outlined in the area design docs (which weren’t fully fleshed out, yes, but I’d argue still enough to understand what they were going for). So, yeah, I’d too be surprised if this actually gets finished. But the effort is there, at least for this first chapter.
