Re: Your points.

1. Not at all. The regents' resources are pretty limited, for one. They need to take personal action in many cases anyway. You also seem to be projecting a modern mindset of delegation onto an older world with a different mindset.

2. I agree.

3. Not really. You need to keep the restraints of the world in mind as much as anything; making the world contain more land does not necessarily create more of an 'epic feel.' The world is not so small as to feel constrained, yet not too large, either. Keep the perspective of the inhabitants in mind as well. Compared to today's people, the people of Cerilia must be fairly introverted; trade and contact with other continents is minimal. If you think of the world as something you have to walk around in, or ride in, I think you'll see that it's a fairly large world.

I'd be more concerned about population size than geographical size. Compared to France from even before the Roman times, Anuire is very sparsely populated, for instance. If you increase the area without inflating the population, the country becomes a wasteland. Population needs to be increased before area if you want to approximate the 'real world' better.

As for the armies being too fast, well, think of Alexander the Great. He conquered a rather large area in a very brief time as well. The political circumstances were different, but I don't see why Cerilia would be different here. If a ruler gets the ball rolling, he could theoretically conquer a large area very quickly. I'm actually more troubled by how _difficult_ that is, than how _easy_ it is, with the investiture rules as they are. The rules resist large-scale quick gains of territory.

4. I agree.

5. Kings and emperors have, in some periods, had traditions for shifting population masses about. Goes back to the Assyrians and Egyptians, even. But when you consider the pace, and that the population size is non-linear, yes, it is a bit fast. But by domain standards, it's a _huge_ investment, and if a player can afford to make it, something else is broken.
