Multi-endings weren't handled at all in TES as far as I know because there is only one possible way to play the main story in those games... Follow the yellow brick road.
Daggerfall is the only game in the series that had multi-endings, depending on your actions during the main quest (6 or 8, if I recall) :whisper:
:P
I was damn satisfied when my game ended. I didn't explore much with my diplomat-like character simply because he's a diplomat, not an explorer. So I mostly did the main quest and *some* side quests. When I got the 5-10 minutes, very satisfying ending, I rolled in a cowboy/explorer character and I'm now doing what I missed during my first playthrough. And it is like playing the game anew again.
And this time, the cowboy doesn't care about who shot him in the head, because he sees that there are greater matters at hand, such as the Legion invasion.
