I've been searching Roguelikes for a little bit now, and stumbled across Dwarf Fortress. I skipped Fortress Mode for sanitys sake, even though I've heard great things about it. What really intrigued me was the combat system. I know the Adventure Mode is not the main focus of that particular roguelike, but I couldn't help myself. I enjoyed the detail in damaged limbs and levels of pain. It also had an interesting feature where piercing weapons could impale the foe, and you'd have to pull the weapon out, or twist it to inflict pain. Enemys even flew backwards in some instances of being hit with blunt weapons.
So if there are any roguelikes anyone knows of with a similar combat system, I'd greatly appriciate them pointing me in it's direction.
