Higher quality…
*Water
*Coastal areas
*Higher res airport textures (high prio)
*Smarter AI-building algorithms, that also makes "chumps" of forets etc instead of just randomly generating forests on appr locations (see example below, the image ending on "1284152077")
*AI-generated rocks/stones where geodata implyes there could be this kind of features (…2008-43-21-51.jpg")

Making use of highres textures for ground and airports -really- makes you feel how little your plane is, cruising around at the airport. The same comes to flying some hundred-thosand feet high, you really get the sense of going x knots.

I'm going to provide some images to visualise my point:

Thanks again for the time you all put into x-plane and I hope the links give some hint of what I am thinking of, and maybe they also bring some inspration to you!
