I'm continually surprised by how many people don't want there to be a Pagan DLC. I mean it's not like the Mongols or Lithuanians had any bearing on history, right? Or were actually dynastic? No, let's just leave out a fifth of the map area of the game completely and watch them get rolled in 20 years because that's what happened historically.
As it stands right now, the Pagans need it more in game terms, they're really badly represented, while the Republics are just abstracted and kind of passive. At least they survive, though. And no, I'm not at all opposed to a Republic DLC, I just think a Pagan DLC makes more sense with the game and is more badly needed. All that remains to be seen is how they make the Republic theme fit into the dynasty game, or if they just transform it into EU3 1066.
