If you like Isometric Racing games (a very sparce genre), then you might enjoy this. Otherwise, this game is very unlikely to make you a convert. The game is riddled with poor design decisions that include some excessive grinding.
Additionally, visual feedback leaves much to be desired. You'll occasionally go off a jump that was nearly indistinguishable from regular road and be unable to turn while you're flying through the air. Add to this the fact that going anywhere near the walls of the track will lead to certain doom. Clip a cross street corner (even ones that appear to be blocked off by light walls) and you'll lose all speed and get passed by every single AI opponent. Be prepared for them to occasionally ram you in them as well.
Worst of all is the fact that all on track feedback is the same color. Arrows point the way and are centered in the track in light neon blue. Also in neon blue are walls blocking off all other paths. When you're flying along (especially with the higher level cars) there is little time to react, this is where most racing games rely on level design to instinctively lead the player down the right path. The use of the same color for where you can and cannot go has caused more than a few frustrating crashes.
Finally the fact that you are driving through the city means that view of the track and your car is occasionally obscured by buildings (usually several times per race). Had they had the buildings partially transparent when the camera view approaches, it would have been fine, but trying to turn corners or avoid cars blind is unbareable.
Despite all this, the game is somewhat addicting, and it's obvious that the game had a lot of potential. It is disappointing that they squandered so much of it. I can't really recommend it, but it might be worth a try if you can get it at a discout.
