Actually I like like when I take off over city sceneries rather than a empty space outside the airport.
When you take off from New York, even on a default scenery, the area is FAR for being "empty". If anything, is already too full by default.
The original suggest, was that we should offer a 3rd city add-on for NYC area, because the existing ones are not entirely satisfying from a performance point of view, which I don't think it makes much sense.
If you are making an airport in a low VAS area it would be nice to add scenery outside the airport.
There are other developers who are more specialized in improving details in the base scenery, which is why, it's best if we stick strictly to the area of the airport property, in order to have the less possible chance of conflicts, and leave users with the most flexibility in choosing these other add-ons.
