Let me start off by saying this game is fantastic!
Some people lead more towards the Underground titles. However, Carbon was the true Need for Speed experience for me.
Stunning graphics. The visual aspect of the game sure was a step up from the previous Need for Speed titles. So realistic, it was almost like being there.
But as always, throughout these titles, you will find a lot of the same game play. With Carbon you'll be getting a little more bang for your buck.
Endless modifications, including performance, visuals, ect. Carbon brings, 'auto sculpting'. This feature allows you to start off with a base body kit, and change it so how you want it.
Aswell as having Auto Sculpting. Carbon gives you Territories, Crews(Ability to hire crew members to race along side you), Free Roam(Drive anywhere you want), Reward Cards(Gain reward cards throughout the game to unlock special features), and much much more.
The cars in Carbon are great. I won't say to much about that. You need to find out for yourself. I will say this, you can get muscle cars. You may or may not be disappointed with the way they handle.
Over all, if you're looking for a fast paced, adrenaline pumping racing game. NFS : Carbon is for you.
