A good adaption from consoles to the PSP, but its not all that good.
The upsides to this game are that there is a vast variety of tournaments to play in and the graphics are great for a PSP game, but these are weighed down by the fact that some of the training sessions are complicated and can be quite difficult to carry out.
Overall this game can be fun to play but at the same time it is pretty lackluster and SEGA could have done better with this. If you are thinking of buying it, I wont try to persuade you out of it, but I would wait for another tennis game to arrive on PSP.
