Archaeogaming Series: What can an archaeologist learn from a computer game?

In this series of posts, I want to test in what capacity a AAA-game in a historical setting can actually teach me – as an aracheologist – something I don’t know about history. I have studied Near Eastern Archaeology, Prehistory and Assyriology, but never Egyptology, what would be the perfect branch of study for this game. Nevertheless I still can learn and by playing Assissins Creed Orgins and researching the scientific facts behind it, I want to find out if the game is well researched and document what I learned from it. Spoilers ahead!
