Desert-themed RPGs?

[aramis erak]

I'm trying to compile a list of desert-themed RPGs or RPGs based in Middle Eastern culture. To be clear, I'm looking for standalone RPGs, not supplements for D&D 5e (or any other existing RPG). The only two that immediately leap to mind are In a Wicked Age and The Nightmares Underneath. What else do I need to be looking at?

Legend of the Burning Sands. Standalone variant core of L5R 3rd, intended to integrate easily with L5R3. non-historical.
