If i want to play this game on xp would it work since the system requirements says that it doesnt need any video card.... and also which one is recommended vista or xp?
It would not work as it need DirectX 9.0c, and anyway it would be very slow. I have a full desktop at house which is running at 3.0GHz with a very high performance vid card and FS X is barely playable. Your best bet is very much bootcamp to play FS X. By the way I have just noticed you are running a MacBook. Forget about FS X, you are better off with FS 2004. Even with bootcamp, your video card is so underpowered you will have to remove a lot of graphic options to run FS X. At which point you will have removed everything graphics which makes FS X such an update from FS2004.
