Still missing fat people. Common 70% of the world population is obese(not really). Where they at?
They must gone extinct. C'mon: 200 years,No food, Being hunted by raiders, legion, mutated beasts, no real medical treatments, general lifespan very short for anyone, Darwin already stated "survival of the fittest". And tha's for the ones left outside the Vaults, where there is rationing, supply issues and if a group of people is expected to survive on the long run they got to stay healthy. And last time I check obesity is not something that's gonna achieve that. Along with the preselection of certain population sectors by Vaultec.
Finally the few that could made it in to the vaults might not been fat at all: year 2077 in a technological advanced pre-war world I think they already found the perfect obesity cure.
I only miss not being able to make a character based on a supermutant skin.
