Got it, and playing it now!
main things to watch out for...it is a resource hog...make sure you have a POWAH-ful computer, or dont bother with it!!
'Gameplay' is the same as any other FS, but the big difference in this release is the 'rewards' for completing the missions...only little badges and medals and stuff, but gives that added incentive to fly them.
GFX are amazing...IF you get the settings right! I had to play with the settings for ages until I got an acceptable balance between framerate and eye-candy. Check out the M$ website to see what they expect it to look like with DirectX 10 when its released!
This REALLY is a problem with FSX, an out of the box install will see framerates of between 5-10 fps, even on an Athlon XP-64 3400+ with a nVidia 6600GT card, but after tweaking, betting 20+fps and still looking good.
hint: turn down the 'Autogen Scenery' to a minimum. and set the water detail to Med-low (2)...that gave me the biggest hit in framerates!
As for online play, works Ok with Gamespy, according to the .nfo file!!
