The Dark Triad gets mentioned a lot, and people talk about machiavellianism quite a bit, but I rarely see narcissism mentioned.

Do you have any experiences with it?

The way I've run game with this lately is to just completely let go of any inhibitions I may have, and fully indulge in my narcissism. Or at least, attempt to.

The result is that I talk to them like they are in children, and they play along. To any outside observer, it would just appear to be incredible levels of obnoxiousness/douchebaggery on my part.

I'll try to experiment more.

Anyway, curious to hear about your results.
