Much bigger(like ACs crowd of ppl:P Some of them should be modelled by designers(quest specific/important/funny/activity specific)but the rest should be generated by software.This should also be improved coz faces in Oblivion are sometimes very funny. The capital city should be huge and the numer of NPCs in it should also been counted in hundreds:P
