There's been a steady stream of adventures from Goodman Games to support their Dungeon Crawl Classics RPG. A few are conversions of older modules written for various editions of Dungeons and Dragons but most are original (very original!).
Many are stand-alone, but there are some linked series and some based in settings other than the 'classic' one, such as the Purple Planet series.
