You know how some games grade your performance in a fight/mission and an S-Rank is awarded for a flawless execution (sometimes even an SS)? What's the S supposed to stand for and how did the practice come to be? I've been looking around the internet for a while and can't seem to find a definitive explanation.
Even if you don't know for sure your theories would be much appreciated.
