Dungeon Crawl Classics, Delving Deeper, OSRIC if you've got the autism for it. Shadowdark is poorly balanced as far as I can tell, and even though that's not as important with this kind of game it will eventually start to make stretch marks in a serious campaign. Plus, mudcore city dude! And not even diving in vats of bloody orc fetuses edgy mudcore like Mork Borg, it's just generic rats and ogres forever.
