Which, since you won't name said source, we just have to take your word for it.
Well, I look forward to Civ7 having the most nationalist interpretation of Persia, China, and India for playable civs--or will we get one civ per expansion, with China in the base game, saving Persia for XP1 and India for XP2?

Civ3 showed that just changing leader
costumes by era was a bad idea; changing leaders entirely per era is a train wreck in the making. I can appreciate that history is more flavor than substance in Civ, but I won't buy a game that indulges nationalist fantasies like "Babylon is ancient Iraq" (or "Iraq is modern Babylon"). I can appreciate that the marketing department insists on some level of pandering, but there are lines that shouldn't be crossed.
