The high trees actually might help. Something to alter it from being typical Earth generally is interesting. As Bingowings pointed out, the desert in ANH had two suns and more than one moon unlike Earth.

Thinking about it, I probably am very biased since I live about an hour away from some of the forests used in ROTJ... That's probably why they seem so un-exotic. :)

Thank you for seeing the point behind my post.

I don't think George Lucas has the entire world in mind exactly when he makes these movies, but it still doesn't change the fact that when I was deployed to the desert in 2006 I couldn't help but notice that all the smaller towns all looked like Mos Eisley.

Those people must have thought Tatooine was really boring when they saw STAR WARS
