and it would give a lot of extra regions :D
sounds tempting but I'm a: curious about a different use for psfs and b: don't know how a player controlled steppe warlord should assemble anything above the starting army or replace casualties.

on topic: there will have been several little settlements throughout a steppe region but the same goes for "civilised" regions with dozens of not depicted cities and little villages with still a higher population of a steppe camp, so probably there are about the same amount(tho I would rather estimate even more) of settlements in a region of greece and a steppe region due to lesser density.
