I just got the flight simulator x not long ago. So far it looks ok but it is a pretty big file. It comes on 2 DVDs and here are the specs for it. RAM:Windows xp sp2 - 256 MBWindows Vista - 512 MBProzessor:1.0 GHzHarddrive: 15 GBOnline/Multiplayer:56.6 Kbps or moreCompatible with DirectX9What you need for sound:Hardware and Soundcard with Speakers and/or HeadphonesGrafic card:DirectX 9.0c compatible grafic card with 32 MB RAM and Compatibilty for Hardware transformation and light effectIt is pretty easy to fly, you can use a joystick, mouse, keyboard or Xbox 360° Controller for Windows. It has a some airplanes, helicopters, gliders and etc.. to fly. As far as I know there is one update so far and there are a few other bugs that they are working on. There are plenty of other extras but to many to list here. As far as paying around $70 for I do not know yet if it is really worth it. Luckily I won it in a contest, so I did not have to pay for it. I can not understand how a game can cost almost the same price as a OS. I miss the days of $15 to $30 games. Hope the information helped. Bye
