I really liked the Fallout 2 style, where at the end of the game it ran through each community and its eventual fate based on your actions. It could leave a rather checkered history depending how you went about things, rather than simply a "good" ending and "evil" ending.
The game as a whole was pretty open ended too. There aren't many games were you can just beeline to the end right after you leave the starting place. Not that you'd ever manage this on your first playthrough.
Overall wonderful game.
