I prefer racing sims that are as realistic as possible, so this game is exactly what I love to play. You will be challenged with this one. The Championship mode does not have a lot of depth but I love trying to improve my best lap ranking against others. If this game crashes on you, its because your hardware cannot handle the high-def graphics of this beautiful racing sim. I have a 4S iPhone and have not experienced any problems yet. I do not have any regrets about paying $4.99 for it. If you prefer realistic racing sims, this is a must, along with Firemints Real Racing. (And there are no in-game purchase annoyances!)
