Even with the control and animation issues, matches are still incredibly easy. Your artificial opponents do not understand how to win a tennis match. They'll hit the ball hard, but they are mostly content with staying on the baseline rather than trying anything tricky to get one past you. However, in the infrequent moments when the computer tries a different strategy, it only cements how broken the tennis mechanics are. AI opponents will sometimes rush the net immediately after they serve, which all but ensures they will win the point. It's impossible to hit the ball around them because of the imprecise controls and the computer's ability to magically slide. Also, trying to lob it over their heads will only result in a devastating smash attack. You have to hope they miss an easy shot or they'll win the point every time. Because they aren't smart enough to consistently employ the only strategy that works for them, you'll still be able to breeze through the ranks with little difficulty.
The computer becomes an impossible juggernaut at the net.
You'll spend most of your time in Pro Tour mode, and thankfully, it has a number of different options to keep things varied. You can compete in tournaments, train your character, try to raise your popularity in charity events, and earn sponsors. The finicky controls make the training and sponsor events particularly annoying, though. These ask you to complete tasks within a short time limit, such as hitting targets, and they can be maddeningly frustrating. The sponsor events are much more engaging since they're more about spectacle than fair competition. For instance, you'll be asked to win five points competing against a pair of opponents. At the very least, these add some much needed variety when you need a break from the tournaments.
Smash Court Tennis 3 has too many flaws to make for a satisfying tennis experience. Even the online play is so overloaded with lag that it becomes far more frustrating than fun. Building your own character and moving through the ranks has its own charm, but the on-the-court action is too unpredictable and shallow to hold your interest long. There are simply too many unforced errors here.
