I've noticed that the better players tend to hit out less often, and the higher the difficulty the more consistant they are. I really would like a way to edit "consistancy". This is crucial to make a true tennis simulation, since there are many players who can hit just as hard as the top players, but are much less consistant. In this game, you either have 80% or 40% on forehand, and I assume that is only for power. Please, please if you could let "consistancy" be editable that would improve this game so much. I already love it, but that would bring it to a new level that I have never seen before (please try).
Another quick question. How can court surfaces (the bounce/speed, not appearence) be changed? This would also make the game more user friendly and another huge bonus for editors.
