You had me at John Carpenter's The Thing meets Alien, since those are two of my favorite films. This seems like a good list, but I don't think I own more than a few things for AD&D 2nd edition.
Do you blog RPG reviews of newer (but old school) products? Because I'm a small time self-publisher who has some stuff I'd like reviewed.
