If you're into some good reads, look at the "Stories from the Front" thread. There are many experiences in game described by the devs, beta testers, and players. I saved a lot from the forum at SOH and will be posting more of them. Some actually had the feeling of being "hunted" by the AI. When BHaH was first released the AI was better than OFF Phase 2, but since the 1.25 patch, the AI is as deadly as the real thing! I won't lie to you, there are a few minor glitches etc, but the OFF team are working hard, producing patches to fix almost anything that is found. You won't find better game support anywhere. Between the OFF team (many of whom frequent the forum) and the many fans of OFF, most any problem you may have can be quickly overcome.
If you are undecided and would like a small taste of OFF, albeit not as good as BHaH, I could send you a DVD of OFF Phase 2 for free. If that's what you decide to do just remember that BHaH is far and away superior to Phase 2. Phase 2 is still a kick. I flew it for a year and a half and never tired of it.
