[@gaudi] The 2000s were a confusing time.

Well you can have someone with no abilities but the primary draw is that your character was involved somehow in that whole world, so if your character is normal they should have some sort of useful skill like being a doctor or a marksman. There are patrol guards, wall guards, scavengers, medical personnel, salvage truck drivers, agriculture, mechanics, builders, maintenance personnel, weapon constructors, probably more I'm forgetting and people can probably come up with jobs I wouldn't have thought of. 

We are not that far into Post-Apocalypse, 500 days or so, but holding on to civilization is pretty important. There is a library as well enterprising survivors who've converted space into places of worship as well as others who organize entertainment like music and live performance. The power is still running so there are films and music you can play but obviously nothing new is being made.
