By real life i mean the real world fighting thing. e.g Like in reality, elbows and kness are more vicious than punches and kicks, which are more damaging than even with somewhat less force, but due to low range it can mainly be implemented on close contacts. So in the game upto maximum possibility it should be based on such type of real life things. you can't make it like, a good boxer knocks out everyperson in a game and say its just a game and here boxing has more priority.
and im not trying to draw the real life statistics of a person in the game. The game structure or engine, whatever, will take care of it . Im just tryng to make a point on how the game should keep things on real life possiblities and that you cant alter it by what it is not but to question the same if its not happening. And iam just presenting an idea that how it should be and everything is on the way, the game engine works.
