I enjoy simple but unique characters. I'm not a good story teller, nor do I enjoy writing roles. If anything they're more of a chore, and I don't want to bore the reader either.

One maybe two entries to introduce the character as with as few words as possible, and give reasons for his actions, then the rare update as he ages with regards to cabal induction, etc. That's not to say my characters are simple themselves, I've come runner up in role contests before, but only because the idea was clever/unique, not because the story was enjoyable.
