E.g., like Assassins Creed Origins’ museum mode where you could learn about Egypt. Less so things like Hearts of Iron or Crusader Kings.
There’s plenty of educational games aimed at elementary school students, but I’m curious if there are any aimed at older audiences, like the game equivalent of a nonfiction book.
How about Hyperbolica and 4D Golf? Both are by the same developer and show you exotic geometry by putting you in there.
Hyperbolica is set in a world in hyperbolic space, where there’s more “space” in your space. Parallel lines curve away from each other and six squares can share a corner instead of four. You learn about the properties of hyperbolic space by trying various mundane tasks like hiking and serving dishes at a restaurant.
4D Golf is mini golf in four spatial dimensions. You build up an intuition for navigating the courses. There’s even a level editor!
Can confirm, 4D golf is awesome. It’s a nightmare to play and you will feel dumb when you can’t comprehend which way is forward but it’s a really cool experience to see what a 4th dimension would look like in practice.
