High Quality Content by WIKIPEDIA articles! In some role-playing games, alignment is a categorisation of the moral and ethical perspective of the player characters, non-player characters, monsters, and societies in the game. Not all role-playing games have such a system, and some narrativist role-players consider such a restriction on their characters' outlook on life to be overly constraining. However, some regard a concept of alignment to be essential to role-playing, since they regard role-playing as an exploration of the themes of good and evil.
