Unsung
A narrative game with no defined setting¸ but focuses on situation where the character make tough moral and ethical choices under pressure -- such as inner city police¸ American soldiers in the Vietnam War¸ or the American Civil War. It uses a simple one-die mechanic¸ where a loss during a stressful situation means that the other players may decide what happens to the character. - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H.
