Stick to Top Spin Don't waste time and money on this one.
First off, Graphics are horrible!!!!! OMG!!! with all the technology out there, you could expect to have a much better level of realism when creating your character!! i played with graphics set to the max, and didn't see any improvement over VT3.
Audio is just a joke! when you start off a match you have this annoying music in the background, and the sound effects are just lame! raquet sounds broken!! players voices are the same in VT3, referee is the same, crowd is just not there... simply horrible sound.
World tour mode, has nothing new, except for a couple of mini games, and the fact that you have to pass from amateur ranking to Professional ranking, the rest is just Virtually the same to me.
Sega still doesn't have license over the big ATP circuits, wich also makes the game feel a little empty, unlike Top Spin... us gamers love to see some branding, especially on a sports game.
In general, i was waiting for this game for a long time, but its just a big disappointment.
