Pros: 2 DVDs as opposed to 4 CD's. Protective case. Nice interface.
Cons: Processor and graphics hog. High end PC's can't even handle this game.

Functionality is all the same (option settings, controls, etc), new planes, new layouts, and promises to be an improvement. However, I spend more time tweaking the game enough to just "get by" than playing it. Its frustrating to have a setup like mine thinking I can handle any game at high or max settings and still register less than 10 fps in FSX. I'm running Asus P5N with Core2 Duo 3 gig 1066 fsb, XFX 7950 GT Nvidia graphics, 2 gig Ram OC, water cooled. Play FSX and I feel I'm running a 486 PC. I don't play it much anymore. reverting back to FS2004.
