Amazon has Rise of Flight: The First Great Air War for PC for $37 with free shipping.
Product Features:
* Historical references and modern computer graphics were combined to render 125,000 square kilometers of French countryside that is disfigured by a terribly cratered battlefield. Fluffy clouds fill the sky which you can fly into for cover.
* Rain and fog are also modeled in realistic detail making flying even more of a challenge as water drops cover your windscreen or goggles. Advanced graphics featuring moving shadows, depth of field, light bloom and reflections.
* Fly several Single-Player combat missions against a computer opponent. If you feel you have mastered the art of aerial combat you can embark on a Pilot Career and fly a historically accurate Campaign for the French, British, German or American air forces.
* Also included is a very powerful Mission Editor that allows players to design custom missions. The Mission Editor is included on the disk and is accompanied by 150 page instruction guide! There will never be a shortage of missions to fly.
* So hurry! Grab your goggles and silk scarf. Enemy airplanes are approaching. Who will emerge as the next Baron von Richtoven or Eddie Rickenbacker? Is it you?
