Cataclysm: Dark Days Ahead. It's more of a zombie survival game, but boasts probably THE most detailed and robust crafting system amongst roguelikes; has mods that replicate magic and necromancy; and has plenty of medieval / fantasy weaponry to use if one wishes to go that route. Includes things like trying to manage your own camp of survivors and jousting on bicyles, and building your own vehicular death fortress with sawblade guns or catapults on it.
