I am quite sad that these civs are not paid DLC-s. Even 5$ better than free civs. I think this plan is not good for the game in long term. There is 0 profit in it atm. I hope they will add skins or something that can be bought.
This game is has a very good core, it just needs long-term support, but that won’t work without money.
Byzantines are a must. Nords and japanese should totally come to the game, too, but adding ottomans and not byzantines feels like a kick in the balls to any medieval fan. I always craved for a pack of byzantines + turks/ottomans and the fall of Constantinople as a campaign or scenario…
