If you like racing games this is a really good one, it's free, you can earn money for upgrades and buy new cars or just buys stuff through the store. I've playing for a while and have been able to upgrade and get a new car without paying cash, unlike a lot of games today.
You race real people using "time shift" technology, people race and you can race against them in time shift, it's like you are actually in their race but it's a replay of the race, you have full interaction with the other cars, it's really quite cool.
Not to mention I was able to buy "my" car, a 350z and just paint it silver in the game
