Just started my own game... I convinced bum #2 on the beach that killing the head vampire with a holy stake was going to make him human. Or getting a transfusion of three packs of Unicorn blood would do the same.
So far I've sold him two of my blood packs.
I'm running as a female toreadore, to get the booomsticks I seduced my way to the drug dealer and seduced him but drained him dry. I kept both sisters alive, and was able to convince the pawn dealer to sell me guns (thank jesus for taking REALLY high seduction)
