Reincorporation is so central to good stories that I'm amazed at how many games that leaves this to the players to know and achieve. Good stories end when all introduced story elements have been joined together with no loose ends.
Which games do you know that actively support reincorporation? How do they do that?
Examples of reincorporation:
Indiana Jones: First scene establishes that he hates snakes. Later he faces a zillion snakes that he must cross to get the McGuffin.
Star Wars Episode IV: First scene establishes that the Empire is building a death star. It blows up in the climax.
