I’ve heard people suggest historical settings for MMOs as one of the genres that has never been well represented. But if you think that lore fanatics are bad enough in fantasy settings, imagine how bad that might get with real world history.
I think Pirates of the Burning Sea gets around this due to “Hey everyone! Pirates!” and there are some historical settings which get fictionalised so much that everyone knows the genre tropes. But when it comes down to people’s favourite historical periods, they want not only accuracy but their favourite characters to be portrayed “correctly” too. And of course the historical veracity is going to be ruined as soon as other players are allowed in.
It’s a minefield! Having said that, if you could have a game with a historical setting of your choice, which would you choose? (I have a soft spot for the romans…)
