When I run Western League I switch all the League’s toponyms between English and Italian depending on the native language of the players. They are all like lakeend and blackvalley and riverside and so on.

I’m not sure how/why sprinklink bits of culture in the game increases othering. Sure it can become a pastiche, but if you’re obviously and declarately making a pastiche and everybody understand it’s not the real thing, I’m not sure it’s an issue.
