I was really into the old World of Darkness games; got my start playing Werewolf: The Apocalypse, and I still have a bunch of splatbooks (Werewolf, Mummy, Mage, Kindred of the East). I still want to play Mummy: The Resurrection at some point.
I also played a bit of D&D 3.5. Only a little...not that you'd be able to tell if you tripped over my collection of 3.5e sourcebooks (seriously, I'm not missing very many, just five or six off the top of my head).
Sadly, I don't actually know anyone who plays any more, and I'm kind of busy anyway.
