Gran Turismo is an awesome game no doubt, and one of the best racing games ever. Although Gran Turismo 2 has been released for a week now, it still is the second best racing game. Since i already have a copy of GT2, I spell out the differences. GT2 has 500+ cars and 20 tracks, but GT only has 165 cars and 11 tracks. This is a huge difference, but for most racers, GT is enough. There isn't a huge improvement over graphics in the newer version but it has been improved slightly. There are double the license tests, but if you are used to the old license tests, you'll do fine. For advanced racers, you'll opt for GT2. GT is much easier to race compared with GT2 because SONY made the computer racers race harder. The tracks are plenty challenging in the latter version and can at times be frustrating. All old tracks carry over with an addition of a few more new tracks. There is also a rally racing mode which is awesome. There really isn't that much more difference. My advice to all people getting ready to buy the old Gran Turismo: This isn't a bad choice but purchase the second version. It triples the fun and triples the challenge.
