Oh man, this shit would be right up your alley. It's not touristy at all -- I found these places by using the satellite view of Google Maps and scouring the desert for anything that looked weird. Had to rent a car and drive a couple of hours into the desert and then walk for a few more down an old riverbed to get to one of them. Here's what they look like from above:

The formation is on the bottom left, and you can see these big empty spaces that have been cleared of rock. I'm not sure if they're old foundations or if (more modern) nomadic groups just cleared those spaces to use for tents.

Here's a really good example. This isn't the one I hiked to, but it's something like it.
Duuuuuuude, that's amazing and I've lost at least 30 minutes poking around that area on Google Earth.
I'm guessing those long dark strips are potentially dug-out channels? They scream irrigation/aqueducts given how meticulously straight they are... And if so that'd support the idea that the area you visited was once some kind of settlement. They're LONG though...
The one I see starting at the site you went to goes South West about 1,337 meters (~0.83 miles), until I lost track of it in the rockier patch.
But then further South West still there's an even longer parallel set of (assumed) trenches.
I don't think this is the same spot in your second image. They converge at a similar circular arrangement though.

Almost directly pointing towards your first site.
These are about 2,131.12 meters long (~1.32 miles)...
From a wider look at the terrain
I'd hazard to say at one point it had far more water, as those absolutely look like river erosion fingers or whatever you'd call them oh duh, you said it was an old river bed. I think the nearest river on the map is way the fuck over there near Rahat, and while it's not showing me elevation really I'm thinking that's more mountainous.
(EDIT: There's an elevation change that I just noticed on the point-measurement. 1074.95m at the longer set and 1053.87m at your site. Would also suggest they might be to transport water.)
Shit. Maybe I'm lucky I'm a broke introvert with too many children to have hobbies. Otherwise I'd wander off into the world somewhere chasing interesting looking shit and never be seen again.
....The fuck thread is this again? Oh right, video games.
In all honesty an AC game exploring these regions could be super interesting, it's just the whole
how it's funded thing that's weird.
