Anyone who is vaguely familiar with the Philips CD-i will remember the visually stunning CD-i golf game 'The Palm Springs Open'. While the gameplay was a little slow-paced and unresponsive at times, the graphics of The Palm Springs Open really let the CD-i shine. It was also one of the first CD-i titles to hit the system. The game had one main gimmick: It used digitized golf players and also digitized real scenery, mixed with full motion video to make it look like a real game of golf! It was a success on CD-i and Philips was keen on getting more sports games using the same techniques. They collaborated with french CD-i developer Infogrames to produce the first tennis game on CD-i: International Tennis Open. You won't find big tennis players here, and I even think some names are fictional: (Victor Player? Robert Garett?) But it did have in-game commentary from the well-known tennis commentator George Eddy.
If you want to read more about all CD-i games, please read and buy this book by Kieren Hawken about all CD-i games, including high quality commentary on each title:
Have a good preview here and for a few bucks you can enjoy it on the beach as a real CD-i fan!
