What I'm looking for is something I can specify initial parameters; land size, terrain types, resources, population, etc. Then I can advance time for 100 years, 500 years, 1000 years, etc. and get a final result. It should also track major families.
I considered Dwarf Fortress, but I never saw anyplace to specify initial parameters, nor pull final stats.
I also considered Birthright from TSR/WotC, but that has too much bias to the setting. Setting agnostic is best. And the time frame is too small on it.
It also does not necessarily need to be computer based. I can sit down with some dice for a few hours and generate the numbers if needed.
