In any piece of fiction, history is going to be secondary to telling a great story.
When i was a teen i heard whispers of a legendary teacher who used assasins creed in their class to teach history.
But i have never seen it happen or know how viable it is.
I suppose a good teacher can accurately steer the conversation in what the game does right and not the many things it does not.
When the notre dame burned down there were articles about using research from unity to help restore it because they had put so much work in getting it right.
that was a myth. the people in charge of maintaining Notre Dame actually limited how accurate the developers were allowed to make the model in the game, because the exact image of the building is protected by copyright
In terms of background information, the first is relatively accurate for a work of fiction.
It goes downhill from there.
