Obsessed by the Ice

It's no secret that I consider Chaosium's "Beyond the Mountains of Madness" the greatest "Call of Cthulhu" campaign of all time. It's arguably the single finest achievement of the entire tabletop gaming hobby, and one of the direct inspirations for Propnomicon's existence. Christian Lehmann has been posting a detailed recap of his experiences running it over at Yog-Sothoth. It's an an entertaining and enlightening view of why BTMOM is such a treasure. There are spoilers galore, but anyone considering giving it a try in the future will find tons of helpful advice and resources.
