Ok, I'm going to start by saying I play this with the move controllers, not the dualshock/sixaxis controller.
Graphics - 8/10 Not bad graphics at all, but not the best I've ever seen - not as good as the graphics in certain games however. The different locations around the world all look very good.
Gameplay (Move) - 10/10 This is fantastic! I haven't played a better move game, the only problem is you can't control a forehand or backhand. It's like really playing tennis! You can play a variety of shots, eg. topspin, volley.
Game Modes - 9/10 I like the career mode. this is very fun and rewarding climbing your way through the ranks, but it i quite hard with a move controller so I suggest putting the game to easy or very easy. My only complaint is that there are not that many game modes.
Online - 8/10 Just standard online really, a little lag but nothing to really complain about.
Very pleased with this game.
