Among the most popular games for iPhone, racing games are consistently at or near the top of the list. I’m not personally a car guy (if you saw my car, you’d probably understand why), but there are some great examples of hardcore and casual racing games to be found. What’s nice is that not everything you find out there uses the tried-and-true tilt-your-phone steering system, though there are some great entries which are. Makes me want to roll down the window and enjoy the spring air while burning up the track.
