I've always enjoyed playing tennis games on the PC when I'm actually able to find a working one and this is no exception. This is a nice little game endorsed by Jimmy Connors himself. It has a great number of options in the game which allows you to either play against a human, or a computer. You also get the option of playing singles/doubles, and the type of court you get to play on i.e. grass, clay, hard.
The controls are quick tricky to master, but once you have it under control it makes beating your oponent much easier. The joystick controls I didn't try, but with the keyboard - when serving, you need to hold down the enter key and then position the circle where you want the ball to land. Sounds easy doesn't it? It's not. Once the ball is in play, simply use the enter key to hit the ball.
Quite nice graphics in the game, too. And with the option to play in a tournament and play for prize money this is definitely a game that can keep you occupied for hours on end.
