Firstly, SAMGTFC... Yes, this does have online play.
Secondly, BRADLEY9999... Yes, you do hit a ball and move left and right, very clever! Considering it IS a TENNIS GAME, are you expecting to see a Hedgehog and a Monkey running around on the court?!
I think this game is brilliant, definitely something I've been waiting for. Virtua Tennis was not much more than hitting the same button to return the ball and didn't require much skill.
It has alot of famous tennis players in the game, like Federer and Nadal. Also has legendary players like Boris Becker and Mark Philippoussis.
This game is all about timing - the sooner you press the button, the more power it builds up, and you have to release it bang on time as the ball reaches you. If you release the button too early/late, it can cause the ball to hit the net or go out of play.
Using each button gives you a different shot type, ie. "top spin" ;) lob, slice, drop, etc. You can even use the right analogue stick for shots, but only for lob/drop shots, and serves.
You can use the R2 and L2 buttons to perform a powerful/accurate shot.
This game is the Pro Evo of tennis games - realistic and takes time to perfect it!!
This is by far the best tennis game anyone could own.
