In August the software giant will release the most impressive version of Flight Simulator to date. The release of Microsoft Flight Simulator 2004: A Century of Flight will coincide with both the 100th anniversary of powered flight and the 20th anniversary of this respected series. And if the version we played is any indication, it may offer the most comprehensive and believable civilian flight experience in any PC game to date. Just check the numbers: For instance, Microsoft has upped the number of operable airports from 22,000 to an even more impressive 24,000. More importantly, the company has increased the number of flyable aircraft by nine, from 15 to 24. And these aren't just any old aircraft, either. With Flight Simulator 2004, Microsoft will attempt to chronicle and celebrate the beginnings of our love affair with modern-day airborne transportation.
