Lots. To narrow it down some, though...
1. Natural places with broken-down machinery, minus the dark atmosphere that often goes along with this concept, and preferably with lonely, atmospheric wind blowing (examples: all of Riven [http://www.mystjourney.com/img/screenshots/riven-56.jpg], and Lehon in KOTOR [http://images.wikia.com/starwars/images/f/fb/RakataPrimeConcept.jpg]).
2. Peaceful, misty deciduous forests with green rivers and, preferably, rafts (example: Carpenters' Landing in FFXI [http://img.photobucket.com/albums/v123/valkea_lumme/FFXI/img_20070521_195824.png]).
3. Enormous waterfalls (example: Misareaux Coast in FFXI [http://img.photobucket.com/albums/v123/valkea_lumme/FFXI/img_20080309_152738.png]).
4. Hovering landmasses (example: Riverne in FFXI [http://img.photobucket.com/albums/v123/valkea_lumme/FFXI/Riverne2.png]).
(Yeah, I liked FFXI's scenery a lot.)
Also I have no examples for these, but...
5. Extremely tall, steep, snowy mountains.
6. Arctic areas with auroras and ice caves.
7. Any cities with an Arabic feel.
8. Bioluminescent forests.
9. Any place that has an extremely alien feeling to it, like nothing I've ever seen before.
