Simply put, this game isnt very good, at all.
Story - You play a girl named Rena who is an ambulance driver turned amateur/pro race car driver. You compete against other racers to try and make it to the top and become the best racer.
Graphics - The graphics are the only good thing about the game. Not great but not bad either, just good. Good car models and track detail. However the people in the crowd and the trees are all 2D. That makes the game look a bit ugly, but it can be overlooked.
Gameplay - This is where the game completely tanks. The cars in the game control like bricks. They are very difficult to turn and are no fun to race, and the sense of speed doesnt help the game in anyway. The sense of speed is very bad also, when youre going 120mph it looks like youre going 60mph, not very well done at all. The anti lock braking system put on by default doesnt help your racing either. It is clunky and takes some getting used to to control your car properly around turns. However that can be turned off.
Sound - The sound in this game is just as bad as the gameplay. The cars engines sound like electric scooters and the voice acting isnt that hot either. Your pit crew gets annoyingly repetitive and so do the other racers that talk to you throughout the races. The games music isnt all that bad, its just some techno in the background, nothing to write home about, but doesnt really get as annoying as the other drivers.
Length - I never completed the game so I am not sure how long it is, and im sure there arent many other people out there that know how long it is either considering this game isnt worth the money.
Replay Value - Why you would want to come back to this game is beyond me but if you do there are multiple difficulty levels for single player and there is split screen multiplayer too, however with no xboxlive it will be sure to collect dust in no time.
Overall - This game as a whole is not good at all. There are plenty of better games in this genre, and this game should not be bought. Do yourself a favor and steer away from this game.
