Huh, I hadn't seen that, thank you, though the arguments are familiar from a bunch of other stuff I've read - I think the interesting thing is that there's been a good bit of work done practically on the idea of classroom applications of games, some of it with more positive outcomes than others, but what I'm really interested in atm is to see what impact games are having without explicit classroom use or design. The thing is, obviously a teacher using a game, or a researcher sitting someone in front of one, hugely changes the situation when it comes to how much historical validity the player is likely to assign to the game - if you have an authority figure next to you saying "we want to know your thoughts on history from this" it totally changes the mindset.
When thinking more widely about historical accuracy, representation, etc in games, I think that matters a lot. If games do prime people to be more likely to passively accept their proposed models of the past, then that means that historians potentially have a much more important role to play in talking to game devs about the mechanical design of what they're doing. If that isn't the case, then that should also influence what historians' interactions with gamers and gaming communities look like and get people to look at other areas and ways to engage with gamers. One thing that's frustrating me when looking at research on this is that there's just not enough done on how games influence people, so there's lots of clever and good work done on discussing how game rules represent the world, but beyond attempts to use games in a classroom context there's really not enough there on why and when game presentation/mechanics matter and whether they influence how gamers think about the past. Bits of related stuff are obvious and well researched (representation of diverse experiences and look being good for people's identification with stories and self esteem, on the side where things can make a difference, and on the other hand the well-debunked games = violence stuff). But I feel like there's a gap for more studies that inform how historians should engage with games more widely.
