http://armorgames.com/play/13530/sands-of-the-coliseumA Berzerk Studio game about gladiators and stuff. It tracks health of the head, body an both arms and legs.
Lost your shield arm? Cannot block or shield bash. Lost your sword arm? Cannot attack normally. Lost a leg? Can't charge at people. Lost any two limbs? Die horribly.
If a limb is disabled, the body starts taking armor-ignoring damage, so you can just disable one enemy and focus on another while he bleeds out.
If the enemy fought hard enough before getting their stuff slapped, the crowd will thumbs them up and ask to spare them. If you subjected them to a curbstomp fight, they will tumbs down and request to kill them. Of course you can forget them and spare the losers anyway, but you won't get the crowd wish bonus.
This game is fun as hell.
