I dont know anyyythhiinnggg about how this might be done but I think it would be good if the cities and settlements could be given more character...

For example: Rome was founded on 7 hills and had rich areas and very poor areas.

I think it would be good if some cities had run down slums with graphitti on the walls etc, maybe messy streets and that type of thing.

I don't think you guys would be able to do this but to me it seems obvious that the appearence and realism of the cities would be improved if some had historically accurate rivers running through them and streams.

I think it would be possible to design slums as one 'building.' Slums should have unorganised messy streets and so the slums shouldnt be organised neatly into a grid like richer parts of some of the settlements.

Would it be possible to have a forum in Rome etc?
