GRID is trully a challenge for every player & be asured the quality of the game is above DIRT's !The review :

User Rating: 9 | Race Driver: GRID PC
In a car racing game the engine is very important so rest asured because the engine is the NEON engine that powered DIRT , but is its much more improved especially in the damage system if you ask me & ot only that i think that its the most gorgeous car racing game engine i have ever seen ...alltough many of you will say GT5 engine is better because the cars are a little better done yes that is true but it does not feature a damage system to the car & the enviroments & crowds !
Gameplay wise the game shines ....very simple control system with each & every car reacting differently + the phisX system is just awsome you feel the impacs as realistcly as posible beetween cars & walls but yes the game is only 50% simulationj & 50% arcade because you can take quaite a beating before your car dies but still after each severe bump your car will control differently & sometimes allmost imposible to drive , probably the thing that sets this game appart is the flashback system just like in Prince of Persia but featured for the 1st time in a racing game & ohh boy this system really changes the tactics of the game in ways that you could not evan imagine & another aspect that makes the atmosphere of this game great is the crowd that wll cover their heads if you crash near them or everytime when you slightly touch a rail or a bump they react "OWWW , AAHHH " it really creates the feeeling that you are there !
Everything about this game is top notch but i have to tell that it can be very frstrating especially with the races at "Le Mans /TOCA etc'" those races are lasting to much & aren't very thriling but frustrating once you nake thaqt mistake because everyone is travveling at 400 km/h !
