1. I think Aerofly could implement rain and snow, giving the game a more realistic touch.
2. I know no one cares but they should make the clouds stay in the same position when moving the outside camera.
3. Be mindful of the ground crew. You can have the pushback take the plane on its own without the hassle of having to do it by indicating which side you want the plane on.
4. You can add a parking indicator, have the plane open the baggage and passenger doors, and provide ground handling. Adding people is optional, except for the parking indicator.
5. I talked about multiplayer and ATC on another occasion, and some people got offended when I mentioned it. I'm fine with the idea of implementing this into the game; it would make it a little more engaging, generate more downloads, and benefit the developers. I understand it can be complicated. Please don't get upset; I'm just giving my opinion.
