If your a first time racing game buyer, don't buy this, at all. Why? It will send you to sleep. The reason behind it? Career mode is mainly challenges that require you to get X amount of Kudos, which you earn from doing drifts and power braking and such, theres races, but if you play on Novice (like me) the game is just too easy, and if you put it on hardcore, the game just becomes frustraiting when your in last place with the guys 30 seconds ahead of you at the START of the race.
The inbetween difficulties are nearly the same as novice for me, except that when you look at the map with each up the guys get slightly closer towards you, On easy theri 1 minute behind, on Normal their about 45, and on hard their 15 seconds behind your guy most of the time, which still makes the game dull because you have 15 seconds relax time, so if you screw up you can get your car going while still being 10 seconds ahead of the guys, which takes all of the fun out of the game, it will be more of a "make sure you turn the car every once in awhile" affair. I for one have not been able to play this online, but it would probably be a better Career mode, making it worthy to play. The graphics are great, nice to look at and the sounds are note-worthy too.
One of the biggest perks of this game is well, Geometry Wars 1+2 in your garages, its probably the thing I played the most in the game. Theres alot of cars in this game, so if your a car buff you'd love it, but if you don't know anything about cars, you'll more than likely just buy the coolest looking one that you can find, but is really worse then the car that costs 1/2 that but costs alot less.
The game has quite a few good points too it (Geometry Wars, awsome graphics, awsome cars, fun races if you go slower than the norm) but the bad out weighs the good to me. (Theres a wide differnce between Hard mode and hardcore mode, You'll ALWAYS be in first for 9/10 of the game, cool looking cars are worse then the ugly ones.) Another really cool feature of the game though, is Gotham TV, which allows you to watch other people in Xbox Live, play the game and see how the race (maybe even improve your own style because of it too) which is nice if you want some downtime in between too easy races, and Geometry wars.
