Feels like a Vault-Tec experiment presented as a roleplay. Neat.

I'm really looking for something with a driving plot, though, something to strive towards. I love the setting, and the narrative has been presented beautifully so far, but it's basically 'fend for yourself' at the moment, which is fine in some contexts, where ambient AI is greater (or even exists) and the direct control one has of one's surroundings and settings is limited (or even null). In a written, narrative format, there's very little tension about keeping yourself alive to keep driving you forwards, because you can literally write yourself out of danger.

If an over-arching plot was introduced, or the RP took on some tabletop mechanics towards surviving, then this would definitely grab my attention by the short ones.
