GMing: Dragons Options

[Lugburz]

So before I say anything, there's a very small handful of you out there who will know who I am, what I am asking about, and why. You know who you are. You might want to sit this one out. Thanks.


All right. So I have this game thing in the works and I'm considering Dragons and shadowy behind-the-scenes Dragon influence for some unthinkable reason. I'm reluctant to take things in this direction because depending on the Dragon, there's not really anything the PCs can DO about it if the monster decides to split hairs with them. I would like to not stick them in a hard place that way. (Better that it be the regular kind of hard place, wherein they must make some tough decisions.) Dragons of the Sixth World has been pretty helpful so far, but an insider's experience and input would be greatly appreciated. Our group has pretty much stayed away from Dragons for as long as I can remember, so no particular relevant experience there. Can't help but think there's a reason for that...

So, what I mean to ask is this: What can Dragons add to a world or a campaign that is fun, interesting, and hopefully not too cliche? Have any of you ever had a "Surprise, Dragon!" moment in a game that was actually pretty cool, and why? Is there anything not previously mentioned that should be seriously considered?

Thanks in advance for the help. Let 'er rip.
