Are there any games where your character has to pretend to be someone he's not as a major aspect of the gameplay? Something like being an undead in a city of paladins, member of some organisation in an enemy country or a non-obvious Jew in 3rd Reich controlled territories? Where you have to cover your tracks whenever you do something and learn what is common knowledge, habits, traditions and so on, all the things you'd need to blend in.
There was something similar in some rpgs (don't remember which though), where revealing who you are could cause you some troubles, like an ambush or some characters would outright attack you; but this sparse, what I mean is a game that mainly revolves around this concept. We Happy Few seemed to go for this, but did they manage to make it good or is it shit?
