I tried one day to think how much programming is needed to create a real 'smart' game that consider any aspect of the game and make it as real as possible.
At the end i realized that no one can make it like a real game because a real game is not a computer game.
In real life you are talking about humans with feelings, about momentum about newspaper with gossip and headlines and many extra things that influence the game.
So it doesn't really matter what are the criteria for the rates because like in real life you cannot expect the unexpected.

do you get me?
