I was reading v2.0 today to try to work out how Frontier Walls work.
Firstly, I wonder whether the rules contain a typo. On page 12, under
Fortification or Obstacle Sections it says
Permanent fortifications (PF) to cover the front of 1 element
at a cost of 1 AP. So far so good. But the next line says
Adjustment if an outside wall of a raised PF tower
at a cost of +1 AP. Should "of" be "or"? As written, that line doesn't make sense to me. But if corrected, it raises the question of what an "outside wall" actually is. Is it defined anywhere? Does a Frontier Wall count as an "outside wall"? Is the cost of a FW section 1AP or 2AP?
So now we go to page 19, and the description of FWs under BUAs. In summary,
A BUA can be...a PF Frontier Wall [FW] (such as the Great Wall of China or Hadrian's Wall) up to 160p wide, between 2 short battlefield edges and 240-400p short of the table centre line. A FW can contain 0-2 free external lining roads and be passed through by a river.
There then follow a number of restrictions on the placement of BUAs which can only apply to BUA BUAs, not FW BUAs. The next question is what external lining roads are, and what restrictions there are on placing them?
Were these rules play tested before publication? If so, can anyone describe their experiences?
