If you haven't figured it out already,
US Open 2002 is a tennis game, and a basic one at that. You won't find anything here that you can't get in any first rate tennis game. Singles, doubles, tournaments, and even a create-a-player mode are available. These options aren't unheard of, but at least they're present here.
The single player mode gives you around 10 international players to use - both men and women - in either the arcade or through a series of tournaments. You can either opt for singles or doubles, which varies the gameplay a bit.
Apart from taking one of these world-renowned players on a tour de force of championships offered, you can make your own player. However, the options aren't as in depth here as in other games. First off, there are only a handful of body styles to choose from, not doing much for character variety. Skills are altered by choosing which ones you want to be proficient in and then taking your player through some extremely boring practice sessions. A good feature in theory, but in this case, the execution of it could have used a lot more depth.
The last hope to stretch out the playability of this game is its Multiplayer option. It's a good idea, but have fun trying to find anybody actually playing on the internet. Finding a server up is about as common as finding a water fountain in the Sahara.
