Instead of the boring and repeated textures tiles in X-Plane, X-Italy hosts a full coverage photoreal terrain for X-Plane 9. I linked to the English translated webpage, original URL is http://www.x-italy.it/index.html.
The large scenery is divided in regions and there’s already the X-Plane 10 update. Price ? It’s freeware. Say… thanks you ! Be warned all their webpages are written in Italian, but remember online translation tools exist for free.
