Here's a couple of quotes from a thread I just read at rpg.net. I think this is a great idea, and I'd like to hear some thoughts on it here, if anyone cares to comment. The thread over there had some great replies, but also got bogged down in esoterica and discussions on what's scary and what ain't.

So I guess I've already done it, in some ways, to my satisfaction. What have others done, and why?
I've decided I want a new Mythos. The old one's fine, but at this point, mouldy old texts in Arabic get the same reaction from my players that a duplicitous Mr. Johnson or an old guy in a tavern with a job for your party do. Yeah, Cthulhu's still scary, but he's scary like Fonzie is cool -- you can remember when he sent chills up your spine, but now he's just Henry Winkler with tentacles.
Although I did include one of the quotes from that discussion, because it sums up my feelings quite well. My own "new" Mythos is more traditionally fiendish in many ways, Armies of the Abyss meets Warhammer chaos gods or some such. To me, that's much more compelling that a tentacled Henry Winkler, so to speak.Bah, and a humbug. The familiar is the only source of fear. It's the familiar defying the "natural order" that scares the crap out of you.
That's why 100' tall tentacled beasts moving in noneuclidian dimensions bore you to tears. You can't even imagine them properly. Thus, they ain't scary.
