That's becoming a FAQ...
The majority of users fly in their local area, or at least their country, only a minority flies everywhere, and there aren't enough customers in Italy to make such scenery commercially viable, and the minority of non-italian customers that will buy the scenery is not enough to offset this.
We made several italian sceneries in the past, including Rome Fiumicino but, none of them has sold in meaningful numbers, one that was a moderate "success" (not really a success, but a bit less of a disaster than usual) was Aviano which, guess what, it's not really an italian airport, and has some appeal outside the italian public. This fits with the above analysis.
We have an italian airport, Florence, sold by Aerosoft, which is nicely done, very good on fps, it's a challenging approach, includes the whole city in 3d, it's one of the most famous italian cities in the world, and the experience of coming down on that short runway with the whole city in view and the Tuscany hills on the background it's really something to behold, yet it hasn't sold in 4 years what JFK or KORD or Zurich sold in the first DAY.
So, those are the hard numbers, a good way to make us reconsider, is simply go out and buy Aerosoft Florence (which was made by FSDT...), we'll certainly notice it, and might change our minds...
