2004 is probably the best one, as there are so many compatable addons from FS2002 as well as it's own. It also does not require a two million dollar computer (COUGH fsx COUGH.)
Meh, since FSX does share some of 2004's code, i think it does work with some 2002
And that's a I THINK, so no "UR WRONG LOLOLOL" Pls.
And also, when it comes to flying, i'd love to have some nice eyecandy.
And wait, Hunter, i thought you had an epic Commodore PC.. of course you can run it.
