Advantages and disadvantages of a desert \ post human wasteland

The above video goes over different post-apocalyptic landscapes in video games. It made me ask the following question. What are the advantages and disadvantages of a desert \ post-human wasteland?

Advantages

• I can use more traditional tropes to the genre like a lack of water

• I could limit the amount of living wildlife due to the harsh environment and lack of resources. This is a traditional motivator for this genre, resource management and fighting over limited supplies (namely wild animals for food).

Disadvantages

• Overused trope. This trope was a result of the fear of nuclear war back in the cold war era. Ever since that time stories have been using the post nuclear desert fallout landscape as the default post-apocalyptic landscape.

• Not a beautiful environment. It is a grim and depressing landscape and tends to shade the feel of the stories that use it. With some notable exceptions: star wars Tatooine
