To find out more about the expansion, IGN managed to get one of the designers, the totally awesomely named Taamati Hanson-Pou, to sound off a bit about the concept and development of the four new campaigns. Today Taamati will be talking about the Britannia campaign, starting with why it was selected and what opportunities it offers. From there the discussion expands to include some new gameplay elements and how the team hopes to include "random" historical events.
You can check out the first part of the blog via the link in the article.
Also be sure to check out the massive video that shows off lots of gameplay from the very campaign they're discussing.
