X-Plane Version 9 took up almost 12gb with the default install and that doesn't include scenery of Asia. I wanted to fly over Manila. That meant installing another 13gb of scenery. Also, X-Plane 9 is Mac OSX and Linux compatible which is probably the reason for all the fanboi junk. It doesn't help that Flight Simulator X was made by MS. OT I confirmed my friend did swipe my Falcon 4.0 (Allied Force) game. He was waving it (the box) at me as he left and said goodbye. I didn't even realize it. No wonder he had an evil grin......
