That's an interesting question for sure. When I raid or PvP, or do anything that interacts with other players, I'm pretty much completely the same person as I am in real life. But when it's just me, playing the game by myself and doing things by myself, my character takes on a life of her own which is an extension of me but not necessarily the same person as me. I have all sorts of outfits, habits, favorite places I go. I have names for my mounts and pets, and dialogues that I'll conduct in /say even if everyone around me is thinking "WTF." I even have theme music and a costume for when I fly around in my Mimiron's head, and I'll go looking for lowbies to buff and help out if they're in trouble. It feels like such a super hero mount, you know?

I did used to play on an RP server before I raided so there is a bit of comfort I've developed to express my character in the game, even if it's just by myself. I am very sentimental about my characters and I have two priests because I wanted to join an Alliance guild but didn't have the heart to faction transfer my blood elf priest to another race. It just didn't seem right. =)

I take a lot of screenshots that kind of... document the life of my character. I made a video out of it last year too. I'll do another one later this year. I'll have to upload it and post it on discopriest.com (my personal blog) so people can see it.
