X-Plane (simulator)
X-Plane is a flight simulator, designed for Mac OS X, but also available for 32/64-Bit Windows and Linux produced by Laminar Research. X-Plane is packaged with several commercial, military and other aircraft as well as basic global scenery which covers most of the earth. X-Plane also ships with other software to build and customize aircraft and scenery. X-Plane also has a plugin architecture that allows users to create their own modules, extending the functionality of the software by letting users create their own worlds or replicas of places on earth.
As of October 2012, the most recent version is X-Plane 10.10. The most recent beta is "X-Plane 10.20" with 64-Bit support. Mobile versions of the game are also available for Android, iOS, and webOS platforms. Version 10.02 comes on 8 dual-layer DVDs, most of which comprise the global scenery, which is 78 GB uncompressed. X-Plane allows flight from 70 degrees south to 74 degrees north. Switching the planet to Mars is an option that comes with X-Plane 9, and although the atmosphere is thin, flight is possible.
