I once used Age of Empires 2 as a way to represent the feudal societies and their organization. I also took a looooong time reading the “history” pages, and took notes based on that for discussion in class.
I was a 10-13 yo boi, tho - problably the only one who ever did that lol.
A lot of games, if used correctly, can help understand the past. Total War games can show how battles took place, aoe1 gives an abstract representation of the classical ages, aoe2 showcases the medieval times, and aoe3 colonial imperialism.
But AoM is the best for learning, in my opinion. EVERYTHING has a description in there. Also the gods and mythologic creatures are loyal to the legends, in both usage and visual models.
I find it interesting how you shared about using aoe1 to teach. Would you care to talk more about that, and how your students reacted? I would love to know how it went.
