I think what he means is that you will actually see the gear and flaps retracting. I previous FS verions, they simply disappear when you retract them.
The game sounds great to me, and a lot more realistic, but can you use downloaded aircraft intended for FS98 and panels in this game? Probably not, if I were to buy it, I would still fly for Delta in FS98. What I meant is that I have just about every upgrade current to FS98, like Airport 2000, ProFlight 98, Flight Shop, EFIS for FS 98, and many others. It's just like working for the airline, with now having ATC chatter from ProFlight 98 and Flight Shop, and lerning to stay on an airway, and if this game is not compatible with those, it will not replace my FS98. For those of you that have FS98 and do not have any of those upgrades, get at least one, you'll notice a marked change in realism!
