It used to stop only about 5% of the time and usually about 45 mins into a game. Now I can't get two minutes into a game before it stops. I tried to reinstall but that didn't help, in fact it wouldn't let me install into my apps folder, I had to pick another. I've sent all the reports to Apple but I'm not sure if that helps or not. I have a quite lengthy crash report that I can post if it helps. Game is 100% original and not a copy.
