I had an idea for the demo of Skyrim:
Why not let us play the story of our hero getting imprisoned?
That way we wouldn′t be spoiler-ed the beginning of Skyrim and we can build our hero before the game comes out (we would just import that character into Skyrim).
Ick. Rather smells of desperation over all the shot-down "Import Oblivion save [character's looks/PC to use as Sheogorath cause, y'know, our last character beat Shivering Isles/so we can "inherit" items from a long-lost ancestor]" to me.
I know that there will probably no demo at all because the game is so big, but I think my idea would solve that problem.
Based on past experience with Bethesda, rest assured there's no "probably" to it and not for any reasons your idea would "solve."
I'd suggest forgetting about the demo that won't happen and waiting for the game's release myself. :shrug:
