The book has a multitude of characters, all with different view points and provides a thoroughly interesting read.
i would love to see skyrims plot behave something like this, having you communicate with an even mix of different characters such as high ranking generals wanting strategic advice to widows seeking news of their lovers death.
in my opinion, it would be more immersive than just following one quest line from one group like you did in oblivions main quest, and give you more of a perspective on the cause and effect of the actions that you or other major characters do.
let me know what you think of this, or if you have any plot idea of your own
cheers
