Or would you rather roam the endless dessert endlessly.
Well I'd quite like to roam the desert endlessly, not quite

However in Tattooine it's not so much the edges of the Dune Sea that jar, it's the exhaustion zones seperating the towns, and worse the one seperating the Agent quest area in the corner of the Dune Sea.
These are as bad at the one that kills you half way across an ankle deep "lake" in Balmorra.
