Thief series.
In the hardest difficulty setting, killing humans is almost always forbidden, and even in the few cases you can do it, your character has no armour and must rely on stealth or long range bow, but in the latter case, aiming with the arrow nocked will tire your arm after a little time. Fighting at close quarters with one foe will surely result in getting damage, with more than one, almost surely death. Also, some missions even require to not only not killing humans, but avoid being seen by anybody and even forbid what is normally allowed, knocking people out. When allowed to knock up people you even must be sure to hide them, not only in dark places where other people cannot see them, but also in safe places to avoid harming them, as should they die, the mission fails. So you are really forced to avoid fights and be stealthy, and the adrenaline and thrill will always come not from fights, but concentration and care to remain unseen and fear of being spotted.
