Totaly non Birthright but....I was going through my Basement and was truely staggered by the amount of Game materials and the number of different systems I have "Crap" for. (And a lot of it is crap)

Had a fish tank not ruptured some decades ago and destroyed about 1/2 of what I had at that point I would likely need another basement...

Traveller (From the original little pamphlet style books through to the new 2320 D20 system), Twilight 2000, Shadow Run, Rune Quest, Chivalry and Sorcery, Pendragon, Chill, Vampire, Werewolf, ARS Magica, Legend of the Five Rings, D&D, AD&D, D&D 3.0, D&D 3.5, OGL stuff out the...., and tons of little stuff that was never really supported.

What do the rest of you posess in your "Gaming Library"...any Guilty Pleasures?
