Besides, I think it would be harder to survive in Death Valley, than it would in some beautiful orchard.
There were a few that weren't based in the desert BTW. Waterworld, and Nemesis come to mind.
Then why would people go there? I didn't take Waterworld as an example, because of it's untraditional PA, as the entire world looked exactly the same (water, well everywhere). I take back the fact that ALL games take place in the desert, but many do.
I'm not saying they should stay in big cities, that's equally stupid, but there are several things between big cities and deserts. And radiation wouldn't be much more significant in a forest. The winds would've dispersed it all over the continent, and wind contributes a lot to spreading radiation. There's obviously going to be more wind in open flat areas such as deserts than areas with lots of trees.This is just immediately after a nuclear war, however. Immediate radiation dies out pretty fast (at least with conventional nuclear weaponry, I'm assuming they didn't use cobalt bombs).
People live in the desert today, but they're very dependent on contact with the civilized world and the cities. That contact would be severed after any major disaster, and those people would have maybe a few weeks to live before they run out of food (at least most of them). The only advantage I can see with a deserted area is the loneliness, less people around you usually means you're safer.
And the fauna wouldn't have changed much in a forest after a nuclear war. Radiation kills rather than mutate, and if it does mutate, those mutations are random, and makes the individual sterile at best. You'd probably find no fauna at all.
The whole desert thing is a trend that survived from PA movies, and should die out in games, that have so much more potential.
