Summary: This is a pretty fun game. I beat it in about 3 days after playing the first day and then getting instantly hooked. There is one gripe about the game though, you constantly play the same opponents. Ranked 300 in the world you play Andy Roddick and you play him again ranked 15 or so. Of course he is much harder when you're ranked 15 or so but that aspect makes it unreal. Other then that its a very good buy.
Summary: This is by far my favourite game on the PSP! I have spent hours pitting my wits against the World's top players and improving my skills. My only complaint is that when you win new rackets/gear/shoes it can be hard to find them! But this is a small moan about a fantastic game which is so addictice you may forget what normal life is!
