Old World of Darkness
One of the first systems I ever touched outside of D&D. It was instantly classic and new at the same time. While admittedly I am not a huge fan of Vampire at this point I have more than a few ideas for even that. I miss playing. I've played so much Werewolf that I want a change within the OWoD lines. So really looking for any game that isn't Werewolf or a really super talky Vampire game. There are enough conflicts among Vampires to do more than talk is my point.
So in order of preference
1) Mage
2) Vampire
3) Demon
4) pretty much everything else.
