They best storyline for me would have to be fallout 3 because of the many ways you can change the story by your actions in game also the way that your "antics" effect the people and things in the fallout 3 world, also the story line has some rather good twists and shocks.
The worst storyline would have to be the halo series because of its cliché sci-fi storyline and its also very transparent you could guess what the conclusion of Halo 3 was by playing the first level of halo: combat evolved.
