Yes, this is a pretty epic dig, but I said I'd give an update, and I will. So I got an iMac, much, much better specs, but the same problem when I ran the game in VMware Fusion. I got back into the game, and as I played it more and more in VMWare, it seemed to crash in less and less time. Well, it got to the point where I'd experience the original problem reported here in ~5-7 minutes. After some hard work and searching, I set up bootcamp. I ran the game in Bootcamp, and it runs great. Besides some puzzling sound inconsistencies (like doors on cars/trucks or hoses being attached being much louder than sirens, and even that isn't consistent), I can play the game indefinitely without crashes. Anyways, I follow the forums pretty regularly now, looking forward to NY Mod.
