I still find the concept of unit/agent movement restricted to one province per year to be somewhat absurd.

Okay, it makes sense that you can only invade 1 province deep into enemy territory in that space of time - it represents one 'fighting season' and so on - but, within the boundaries of one's own domain, you should be able to move any unit over just about any distance in that time. Maybe a maximum movement allowance (to use boardgame terminology) of 6-10 provinces per year.

We all know about Harold Godwinson marching from Stamford Bridge to Hastings, so 150-200 miles per week isn't unreasonable expectations for an army on foot in those times. How long to walk to the Holy Land from northern Europe, one wonders? One year?

Basically, this is all apropos of the idea that a large standing army was unusual in those days. You'd raise it only when necessary, then march it over whatever distance required to deal with the enemy threat. I suppose, for game purposes, this is a lot harder to simulate.

Would a Chapter House really take 6 years to build, as well? Maybe mod that down to 4 years, or maybe even as little as 2?
