I actually think GURPS has one of the best combat systems in existence, which can be calibrated for a desired level of crunch and lethality as desired. You want unarmed combat attacks to do FP damage? Easy enough to change unarmed damage from crushing to fatigue for living targets and just crushing against nonliving targets (lethal strike would likely change the damage to crushing versus living targets and piercing versus nonliving targets).
