In any event, one of the many cool things about Fallout (which may have been done in previous games that I am ignorant of) is that the choices you made with each city you visited in the game caused a different splash screen at the end of the game, describing what happened to the locale in the future as a result of your actions.

The same sort of effect is present in Kotor2, though it does not only apply to planets and their people, but it also extends to your companions as well, depending on how you treated them or how horribly you broke them to your will - if they survived at all.
