If you look at a Koppen map, you'll notice that large deserts (BW*) tend to run all the way to the ocean unless there are intervening mountains.
Looking at my notes and maps, the prevailing wind should be from the east. The break between the Inter-Tropical Convergence Zone and the Subtropical High Pressure Zone would cross over the land bridge just south of the mountain range. However, due to the high- and low-pressure areas, there would also be a significant wind coming off the western gulf on to the southern part of the landmass. It might be worth examining how these two air flows would interact.
One problem I have is that there is no real-world analog to this part of the continent. It's shape, size and position are difficult to compare, and it's also very far away from any other landmasses on the planet. I think my mindset with the desert was that by the time air from the coast reached the interior it would have lost most of it's moisture. However, you make an excellent point regarding deserts extending to the coast. I'll work on reducing the desert's size when I get home and post what I come up with.

The fact, for instance that you can even see the rivers at this scale is not very realistic, but does make it a more informative map.
I'm trying to strike a balance between the two, as I imagine everyone does. The original idea was to have a realistic "world" map large enough to allow for zooming in for a reasonable approximation of a regional map. In terms of game fiction, Humans would be trying to combine fragmented orbital/aerial imagery with land-based observations as well as information gathered from other sentient races. I imagine such a fusion of information would result in an unsual style of map.
