Sometimes slow loading
Unclear instructions on some of the games.
Handling is somewhat poor.
I picked this game up so that I could play against my friends at school when the teacher was being boring to be honest.
The game is pretty addicting when you first pick it up, being able to train and customize your own characters is always a good quality in a game. You train both a Male and Female character in the World Tour mode of play. As your skills get better, the games get harder. Some of your skills are fairly difficult to level because of the difficulty of the training games, as not all of them have clear instructions, or are just extremely difficult(Mainly the Disc Volley game and the Stroke training games). The tournaments are fun to play in, getting you a higher ranking as you win. The ability to play mixed doubles is fun, being able to combine your 2 trained characters and test them against the opposition(Professional Tennis Players). The cast of characters is a good selection, from Roddick to Sharapova. The customization is fairly good, being able to choose what shirt\shorts\skirt\wristband\tennis racket your character uses is nice. Once you get semi far into the game however, you will become kind of bored, because of the fact tournaments don't come fast enough, and you've already won enough money to buy everything. However if you like Tennis I would highly reccomend you to pick up this game.
