You do know that tennis as a computer game is basically a suped up Pong, right?
You have never played Topspin then. If you are no good at it just say so.
I have this game on pre-order the original is very addictive.
Price wise you don't know how lucky you are in the US.
The price for release here is £43.99, if you pre-order via the net that drops to £39.99 but still a lot more than $39.99 which = £22.91 at the moment
