Yeah. A Birthright campaign setting book would be a great way for WotC to introduce both mass combat rules (which they haven't revisited since that early UA, right?) and rules for building and running a kingdom.It was a setting designed for mass combat rules.
I could see Hasbro being interested in WotC producing a new mass combat boardgame D&D spin-off.
I know almost nothing about Birthright, but reading the preview, Cerilian elves remind me of the ones from Skyrim.
There is very little I would like more than for this to be true, but isn’t this just a release of earlier editions pdfs like a lot of DriveThruRpg.Saw this. Don't see much purpose if it's not for opening up Birthright for DM's Guild
