NaturalMotion is a social gaming company based out of Oxford, England. They have created two of the best racing games available for iOS users. CSR Racing and CSR Classics are drag-racing games that are so deep and entertaining, you can play for hours and not know where the time went. Iconic cars I’ve blogged about like the BMW 507, Lancia Stratos and Nissan Skyline 2000 are all in the CSR Classics version. There is a great mix of both American and foreign cars in both versions of the game. Hundreds of customizing options are there for some fun (and strategic) tuning. One knock on the game is that you have to wait for your fuel to regenerate to race again. For anyone who loves cars and has an iPad or iPhone, this is a must-have app!
