if you like Virtua Tennis, then it's good for you.
Personally, I think it's too arcade oriented, and it's really not a simulation. The sensations have not much to do with the real ones when you have your feet on a court. Moreover, the tournament mode of Tennis Elbow is so more complete than the one of Virtua Tennis...
But if you like Virtua Tennis so much, don't lose your time to write denigrating messages here, and go to play it !
