So a Vault - one of the biggest assets in the series - has never actually been done yet in the games proper. This may be due to the fact that a vault hosts 1,000 people on the normal side, enough for around two barely genetically viable populations. Entire games have had less speaking roles, much less fleshed out characters. But what would a vault look like? Especially with the advancement of gaming technology, maybe one day we might see a properly laden vault. In Fallout 1, we're treated to this: A 10 story vault, in the middle of a mountain, with a nuclear reactor (I'm guessing) on the lowest levels and habitation levels above. Using the game itself as a abbreviation of the vault, the entrance level has a prep room/airlock, the medbay, and the blast door itself. The habitation floors are relatively uniform and sparse, while the lower level is a mix of recreation, energy, and administration. This layout is also the same in 2. Now, 3 sort of flips the layout. There's no concise map for Vault 101, but the reactor is again on the lower levels, the recreation is splattered throughout, and the entrance is a long way off. NV follows this layout. 4 does something interesting. For 4, I'm going to pin the standard as vault 81. It actually seems to be roughly the same size as the vaults in 3, but with a lot more details, along with, well, a population to convey size. It works, though the reactor is right behind the kid's bedroom. So, what do you all think - would a proper vault look like?
