We buy that and we are thinking return, You can't see the software using a normal computer you have to buy first a super computer to run that. The Flight simulator 2004 is better running in a normal PC. you can't see all graphics and detail without a super machine.My machine is a Pentium M 1.7 Ghz 512 Ram, Toshiba Tecra and take 4 hour in the installation process, and 1 complete day to play the simulator.Don't do that to us microsoft please..............
