Im going to say Washington DC from Fallout 3. Fallout 3 is waaaaaay different than New Vegas or 4. The DC area in 3 is barely livable with Super Mutants and Ghouls everywhere, a metro area that really doesnt offer any shelter, and most importantly no clean water.
If the Super Mutants or Ghouls dont tear you limb from limb, the starvation or cancer will get you.
