You should try the need for speed game on Google play. The game is very good and looks good. It takes up a lot of space. But, the game has got a lot of good reviews. It plays like the ps2 version of need for speed. It's worth a try.
Other free games you could download: Race of Champions GT Racing: Motor Academy Raging Thunder Road Warriors A number of the games aren't all that new but they are free. So if you want a free racing game and don't mind when the game was released, download them and find out if they are as good as some say they are.
The only game that has been able to impress me is the Asphalt 8. It has the best graphics. No other game can beat this one. It has a very high rating and almost all the player have been amazed by the quality of this game. If you have not tried the game, you should check it out.
I have played this game many times. It's a quality game but I don't think it can beat the Asphalt series. The asphalt game is much better than this game both in terms of graphics and interface. Almost 90 percent of the reviews of the Asphalt game is positive.
