Looks like some spring cleaning going on over at Goodman Games. Dungeon Crawl Classics, a line of adventures which draw their inspiration from 1st edition AD&D adventures, are 20% till the end of May, online and at participating game shops. I planned on running Idylls of the Rat King at DunDraCon this year, and I played in the Sunken Ziggurat. If you’re really feeling nostalgic, check on the fan conversions to 1st ed on the resources page, and some of the 1st edition adventures here.
