Having played the demo, I'd have to totally disagree with some of rather extreme reviews previously. Yes, the handling in Juiced 2 is a bit more 'arcadey' then Juiced 1, but this just serves to make the game a bit more accessible from the start, with still a great amount of skill and practice required to truly master it.
There's a great variety of races and race modes which you can take both online and off, and drifting is totally addictive whatever mode you're doing. And then there's all the other stuff - loads of cars, mods and a huge decal system so no two cars are the same, spectacular environments, like the sydney opera house and the eiffel tower, online trading of paint jobs, downloading celebrity 'driver dna' and racing them, online pink slip races and more! Well worth the money as it will keep you busy for ages!
