Many people have fond memories of the Xbox classic "Crimson Skies: High Road to Revenge".
Many didn't know, though, that High Road to Revenge is actually a sequel to THIS game, released only on PC way back when. This is a shame, since this original release had even more swashbuckling aerial flair than the Xbox game, a lot of plane customization, and decent story/voice acting. It even had multiplayer mode, with Zeppelin versus Zeppelin combat (though that was only provided via MSN gaming zone, so it hardly ever worked or had players).
It'd be great to see this title resurrected, not only so the xbox fans can experience the prequel story, but also since it's such a well done example of pulp genre fiction.
