I have just bought this game and can't stop playing it. The online feature is fantastic...however, I do feel a lot of sympathy for the people I play againts, as I am not really very good......yet!!!! I have never laughed as much whilst playing doubles on line, although the game does really encourage your competititive side.
I would recommend this game highly and have already convinced two other people to buy it.
Have fun and perhaps see you online!!!!!
