The top Racing Games on Xbox 360

1. Forza Motorsport 3- This game has many number of tracks and cars, also the amazing gameplay complete with tons of difficulty adjustments to ensure players of all skill levels can play

2. Project Gotham Racing 4- It looks better then the previous versions, has a far better car list, has a better career mode, and just plain has more stuff to do. The gameplay is as sharp as ever as well.

3. Dirt 2- Dirt 2 is the best offroad racing game of this gen so far. It takes everything that made the first Dirt good and polishes it even more to produce a bigger, better looking, better playing game that is a must buy for racing fans.

4. Grid- Codemasters has tweaked and tuned the Pro Race Driver series into GRID and turned an enjoyable but niche series into one of the best racers on the market. It straddles the line between simulation and arcade to produce a racer that rewards you for driving correctly, but also doesn’t penalize you if you want to break the wheels loose and throw the car around corners. GRID is just plain fun.

5. F1 2010- There are few gliches but this game is still a good one with a good career

6. Burnout Paradise- EA and Criterion have finally delivered the first true next-gen Burnout, and the results are pretty impressive for the most part. The game maintains the blazingly fast racing, slick visuals, and bone shattering crashes of the past, but adds in a few new bells and whistles to keep the series fresh. Not all of the changes were for the better, however, but even with a few lackluster race modes, Burnout Paradise is still an excellent racing game overall that is worth a look.

7. Split/Second- This is a game about blowing stuff up to not only crash your opponents, but dramatically alter the layout of the entire course. It isn't particularly deep, but when everything clicks together it is amazingly satisfying and fun.

8.  Midnight Club: Los Angeles- The racing is fun. The graphics are gorgeous. And there is a ton of stuff to do. The difficulty level may present a few roadblocks, but for race fans Midnight Club: L.A. is worth a look. 

9.Need For Speed: Most Wanted- It combines the great car customization and open world of Underground with the police chases of Hot Pursuit and the solid racing gameplay that the entire series has been known for. Whether on the Xbox or Xbox 360, Need for Speed Most Wanted is a must play for race fans.
 
10. Blur- Blur takes the best of developer Bizarre Creation's Project Gotham Racing series and mashes it with Mario Kart. Blur is fast paced and fun, but also surprisingly accessible.. The single-player loses steam after a while, but take the game onto Xbox Live and race with up to 20 people and Blur becomes something truly special.
