If you want something truly odd, beautiful appearance vs. ugly appearance.
crater said:I go with this interpretation too. The Unseelie court can be shocking, like a fey freak-show, without actually pinning it down in terms of alignment. The diversity of its bizarre looking members might indicate a chaos tinge however. The Seelie court represents idealised beauty, and has every negative aspect that those who value beauty above all might display.
Kobold Avenger said:I tried thinking of Changeling: the Dreaming's interpretation of the courts, and it seems like it's like many of the points above, except that it sort of could be a little bit of law & chaos.
Anyways I haven't really checked out Bastion Press's Faeries, considering the last book from them I checked out was Airships which was a little too complicated rulewise. However I don't think it has much of a need to make new rules mechanics so it looks like something that would be easier to implement.
Finding Ars Magica stuff is probably going to be hard, but I've heard it was quite a good book to get in the past...
Anyways in my campaign there's only one nation that is declared to be of the Seelie Court and only one nation that is declared to be part of the Unseelie Court. Most of the population of those two nations are elves followed by every other variety of fey, who are by default aligned to the courts. But there's about 50 other nations in the world, and most of them have some form of an elven or fey population who probably wouldn't bother aligning themselves to any of the courts.

Hope I've given someone some good ideas.
