Fallout 3 to have over 200 different endings (also, pet dogs :-))!

No, wait. I just thought of an even easier way to explain this. I'm not sure why I haven't stated it this simply before.

Any time you give the user more power to make the story, the less power the developer has to make the story. You can't have both simultaneously.

We're moving away from story telling. Games will not be like movies or books, where the story is "told" (meaning, transmitted by the developer to the user with input from the user).
