On the one hand I’m glad that the DLC contents have been revealed before release.
On the other, I feel bad for Sar and all those careful marketing plans!
I don’t think they’re being that pedantic with the names, and besides the 1800 Acts of Union were about the annexation of Ireland, something I can see Firaxis avoiding.

Interesting that they've gone specifically with "Great Britain", and not "Britain" or "United Kingdom". Great Britain is defunct as a political entity by 1801, so plenty of 4th age wiggle room there...
