Awesome graphics, great map, really cool cars...
The free roam is awesome, especially online. Going for cruises with random people around the islands hundreds of miles of road is good fun.
The variety of cars is unbelievable, I have trouble picking my favourite ones out there's so many to pick from! And even Ferraris, oh joy! They've finally stopped being so snobbish and agreed to have their cars in a computer game! Although you have to paint it the colours they want rather than just any colour... The character customization is also a cool feature (even though everyone looks pretty similar lol).
But the best thing about this game is the realism. Everything about it is immensely detailed, from the interior of the cars to the way they go around corners.
This game is definately a must if you like racing games.
