Experience Points (or Karma, or Legend-points, etc.) are given as an award to the players that can be used to improve the capabilities of their characters and to monitor general "progress". In all games I know of, the characters don't know in-play about XP. That might result in a discrepancy between the motivations of the player and the character — the player might want to go on the adventure to gain more XP, the character might have no such motivation.
Are there games where the characters know that they will gain something intangible by doing this adventure? Maybe "the goodwill of the gods", or something like that. Which games have such concepts?
