Hmm. It's true that the setting is pretty close - wizards, city guards or heroes. And it'd be meant as an easter egg, so there wouldn't be lore conflicts.
On the whole, maybe it wouldn't hurt TES. If I ever regretted something with the series, it's the lack of distance toward the whole epic hero thing. Worked for
Morrowind, insofar the feel was alien enough to tune it out, and since you spent enough time being a n'wah anyway ;
Oblivion, now... *shrug*
I got amused, the same way I couldn't watch LOTR without cracking jokes every five seconds. Sooooo serious. My chars end up having some major coordination/orientation issues : how the hell can I take all these doom and prophecies things with a straight face ?
Yeah, I get I'm prolly alone thinking so. Maybe a Skyrim equivalent of the Patrician, then ? I sure would enjoy that kind of politics.
