Greetings! Mixing genre for gaming is fun. When I was putting together a Cyberpunk 2020 game that didn't quite get off the ground, I was going to have fun bringing in psionics, magic, superpowers and Cthulu. I think the players just got scared and hid.
Y'all would *really* like Glynn Stewart's Changeling's Fealty series. It's really good urban fantasy with a STRONG flavor of White Wolf in it.
