I don't think there is any one easy answer to your question. I suggest you take a close look at some of the excellent "developer's diaries" found in this forum (if you haven't done so already that is). Reading through them got me excited for some time now. But seeing how AOD is created by hardcore fans of HOI and based on a tested, proven engine, I'm actually much more hopeful for this game than I ever was for HOI 3 (which sadly I still cannot get to run on my half-decent rig

). So if I will be able to run AOD optimally, I definately won't consider it a failure
