Honestly, I think this would make people want to view AAR more then they normally do. I have to disagree that the flat maps reduce the visual appeal of such an AAR. AARs have little to hype them up other then someone attempting to describe the turn beyond who rolled what.
Strange as it sounds, it reminds me of the old Battletech cartoon's CGI cut scenes.
I can only imagine the time it would take to do an entire game, but I'd be sure to check out such AARs even if it were just for the novelty of it all. Stuff like that could help bring in new players, or at least attention to the game if you found a way to spread the word around a shop and gaming forums. O0
