Votes, by accident, much better tactically and better strategically. But thinkin about it, it is perhaps not so far from the truth. I would just prefer something in between better and much better.

I agree with the Grif here. Cities seems to be right on the front all the time, not perhaps attacked, but you feel a need to take action right away as every single city is important.
Also, with the cities farther apart it gives the Hordes some room to play out their game. You can't come to the aid of a city in trouble as easily.
With cities farther apart fieldbattles seem more prolific. I quickly got tired of the constant breaking siege or laying siege with little in between, in RTR.

Meanwhile, how long or much of an impact would the Hordes have if the Goths, Sarmatians, Burgundii and so on all had 3-4 cities? We would see the Hordes blow their steam while those factions would still survive. With few cities the other factions will be forced out and put a much more significant pressure of the two empires.

I simply don't believe more cities are always something good.
