It´s bad because some points are always very similar. For example: I serve nearly the lateral line, and then, I go to the net and I receive with all the court at my dispossicion.
In other way, I love the game. It´s excellent the management situation. You make my dream. If you can do something of the Virtua Tennis style... It´ll be perfect.
