At last, we're up to the top objective of most medieval campaigning: building castles!
Much of the material seen in UWA is borrowed directly from FFC with a few minor tweaks to the cost and size of some items. DD sticks mostly to FFC's 60ft sections of wall, ditch, whatever. Interestingly, neither source comments on the time required to build a castle, although FFC does talk about annual costs, possibly implying that a castle will be built within a year.
FFC's "off the plan" small, medium, and large castles, and UWA's great keep are not listed here, but could be included in an additional table.
My valued members have access to the annotated version, which I hope will be enjoyed :)
Next time, I'll look at the closely related matter of Establishing a Barony...
