Any chances for a game such as Chariots of War 2, ancient Mesopotamian city states fighting each other, building settlements and burning enemy settlements whilst competing for local hegemony?
Any chances for a game based in ancient China, Spring&Autumn eras and Warring States era?
Whilst talking about niches, precolumbian Americas, with different tribes competing and eventually trying to build an empire to rival the Mayan or Aztec Empires of our timeline, whilst preparing to hold off the Europeans once they arrive?
Also, you are still missing a game that would take place between Eu:Rome and Ck2 Old Gods, meaning a game where Roman Empire is slowly crumbling, whilst the Great Migrations will lay the foundations of modern Europe? Good chances for a Late Antiquity - Dark Ages - Ck2- Eu4 - V2 - HoI3 megacampaign.
As for AI, when looking back at old Eu2 or HoI AI, how do you think the AI in your games will improve over the coming years? Human brains always should be able to give the AI a beating, but it should become more challenging if you just somehow manage to make the AI super smart; the AI having evolved quite a lot IMO over the last decade in your games.
What is with the game expansion icons, when you add all possible Eu3 icons together, you could get 6 icons for one game; now with Ck2 getting expansions/DLC with no additional icons forum users are no more gaining icons as easily.
Are you trying to limit the amount of icons released per year? Also new game avatars coming soon?
Eu2, Eu3, Eu:Rome all came with maps; WHERE IS MY EU4 MAP?

I would purchase one from if you were just selling; I'm sure there is some demand for those, and you as a profit seeking company ought to start producing said products
Will custom forum avatars ever return?
Why wasn't Falalan included in Eu4? IMO Eu2 had best music of all Paradox games I have so far played, V1 coming second.
Now that we have been forced to become Steam users due to Eu4, will Paradox continue releasing products that are not Steam-only in the future? Or do you support giving Steam a market monopoly?
