In Player of the Game Tennis, each player is individually rated for their service game both first serves and second serves; their complete ability when receiving (again how they handle the opponent's first serve or second serve); ability to hit game winners or game losers in some cases. Other factors, like a player's fitness, whether he is a favorite, ability to handle adversity, major and minor injuries are all included. Did we mention that all of the factors above are broken down by playing surface? All aspects of a tennis match are covered.
