I guess I could have posted here back when I registered. Oh well...
My first RPG experience happened in the late 70s with a TSR product. I've become acquainted with many, many games since that time, owning far more than I ever played (or needed)...
My first BRP game experience was sometime in 1982 with Call of Cthulhu. I was instantly a fan of the system; it probably helped that I was somewhat obsessed with Lovecraft. The BRP games I currently own are Stormbringer, Nephilim, and Call of Cthulhu. I also have a copy of GORE, which I currently use for my own campaigns.
My favorite games are Worlds Beyond, Fading Suns, the TTA RPG, Traveller, Spacemaster, and Call of Cthulhu.
