This document includes all the rules that are either missing or ambiguous in the documentation for AOE III, the Builder expansion and the Plague Promo.
It is not intended as an FAQ. Most of the material in the existing FAQs covers information that is already in the rules.
Where possible all information has come from answers provided by Glen Drover and Eagle Games, primarily via BoardGameGeek.
Please let me know if you find any errors or omissions and I will update it.
