I actually hated 2000, but love 2002. 2000 ran so damn slow on my system, but 2002 runs great, even with all the settings maxed out. They really must have tweaked the graphics engine for this version. It's much more efficient. I like the new air traffic control, and the graphics are much better than 2000. I don't know what all the differences are, but just the fact that it actually runs smoothly is a reason to buy it (if you like the FS series, of course).
