Pros: Looks fairly good, different courses from Gran Turismo.
Cons: Control becomes an issue for cars with more power.
The bottom line: If you can tolerate the level of difficulty later on, and the lack of technicallity of the courses, Sega GT may be worth a purchase.
Sega needed a game to attract the simulation racers away from Sony's Gran Turismo 2. So in 2000, Sega GT was released. I'm not sure how well it did, but from my experience, it was far from Sony and Polyphony Digital's opus in terms of gameplay and control. It isn't terrible, and in fact it brought along a couple of good ideas such as creating your own car and the licensing tests. But the one thing that really hurts the game, which is it's "fatal flaw" is in the handling physics of the cars. I will get to that in a moment.

Graphics: 7/10
Not terrible, but by no means a beautiful game. When you compare the graphics to other DC racers such as Rush 2049 and Metropolis Street Racer, Sega GT falls behind on looks. For some reason the colors seem a tad too saturated. The green grass looks like sea green. Maybe it's my TV or perhaps it was the fact that they may have designed this for the VGA box. Some textures tend to be flat and blurry, but this is not the case most of the game. Most textures are pretty crisp. The car models are good, not great. GT3 has some of the best car models ever seen in a racing game, and playing Sega GT after GT3, the models seem a little dull. Also, compared to MSR on the Dreamcast, the models seem a little less detailed here. The window reflection is awful, since there is none. Instead of creating a reflective or a faked reflective surface (like in the original SF Rush), the developers just made a texture that LOOKED like a shiny surface. Needless to say, it looks like a few thick white lines. The framerate is respectable and never really lagged down.

Sound: 7/10
If you want licensed music, look somewhere else, because Sega decided to do it themselves. It's ok, but not groundbreaking. What's here is fairly upbeat, japaneese-like pop and rock without lyrics. What racing music used to be like back in the day. The sound effects are decent, and some engines sound different from others, but if your car gets stuck on something, a really obnoxious revving sound is played. It's horrible!

Play Control: 5/10
This is what really hurts Sega GT, the controls. The weaker cars or cars without modifications (up to the point of an Audi A6) handle fine. Put upgraded parts in it or buy a really fast car, and the control goes to hell. Steering becomes way too touchy and almost unplayable. This is the complete opposite of Gran Turismo. The brake is useless, and the only way to turn with some accuracy is with the emergency brake. This does not feel like a racing sim, but an arcade racer trying to be a sim, and at some point, something died.

Gameplay: 8/10
It's pretty much Gran Turismo Lite. The elements are there, just not enough of them. And their definition of an endurance race is pretty funny (only 15 laps?). The license tests are pretty fair, just drive a lap and get the qualifying time. It saves a lot of time and effort. The Carrozeria feature is pretty fun, where you can create a car using the game's options. You can't create your own body, but you can pick from a few (after everything is unlocked, about 12), and you can pick the engine, the engine type, the drivetrain and more.

Replay Value: 7/10
Most of the game can be played without much of a problem, but when the cars start to lose control, that's it.

Overall: 7/10
Sega GT wasn't such a bad game, but they tried too hard at beating Sony in the simulation racing department. It's fun until it becomes intollerable and aggrivating, but not as soon as Vanishing Point did. Decent for those looking for a racing sim and don't have a PS2.
