In 1980, I wrote the roleplaying game "Call of Cthulhu". At that time, everyone I knew who had heard about Lovecraft knew of him because I had told them personally. Lovecraft was vanishingly obscure. Lovecraft was an unknown. I expected Call of Cthulhu to sell a couple thousand copies to the few hard-core Lovecraft fans in the world, and then vanish. I put my heart into it anyway because of my own love for Lovecraft. Instead, the game turned out to promote Lovecraft and spread knowledge of his works. So many folks played Call of Cthulhu. Many more didn't play it, but knew about it. I have had literally thousands of people walk up to me at conventions and tell me that they read Lovecraft after playing Call of Cthulhu. Others (occasionally in tears) told me that they were so excited to see that someone else knew about Lovecraft. This last encounter is now rare, because everyone knows about Lovecraft. It is my proudest achievement to have been a tiny part of helping bring cosmic horror to so many.
