The gameplay that I’ve seen doesn’t feature much religious paraphernalia or foreign subjects. Although I don’t adhere to any particular faith, I can’t help but feel like the game should contain a big dose of religious symbols/events. I can only imagine how influential religion was during the Middle Ages.
As for foreign subjects, I keep thinking of the Ottoman Turks, especially since they were considered “the menace of Europe” for at least three centuries. I know this game takes place in 1403, so that’s still a few decades before the fall of Constantinople, but the inclusion of Turks (and other foreigners) would give the game more “color.”
