This is just a friendly thread. I wanted to see what Chaos God best describes your goals.
For me, it would be Tzeentch. I don't really see myself as a ladies' man, or a big burly guy killing people just because he has psycopathic issues. Nurgle isn't my cup of tea since I'm not a real messy person. Tzeencth interests me because I would love to shoot fire and warp reality in my image (what can I say, I'm evil). I mean, I'm not the coolest kid on the block (but I am getting close), but I am sort of smarter than most kids in my school and the God of Change seems pretty smart, so yeah, I'll go with him.
Edit: I'd like to hear what you chose and why, but of course it's not mandatory.
