don't really play roguelikes as much as i used to, but i still hop into Dungeon Crawl: Stone Soup from time to time. i used to LOVE dwarf fortress, i probably spent several hundred hours on that game in 2005-2006 but my time became less available as the game got more complex and nowadays the various subsystems are just too much for me. i also used to love IVAN, Nethack, and casually played Angband, Incursion, TOME, and others.
surprised not to hear more love for Caves of Qud, other than Unreal World I would say it's the most interesting RL around currently
