The only possible comparison between those two games is about graphics and context. In terms of writing and everything else, Desert Stalker is just untouchable (too few games with that kind of quality, whatever the kinks). Hot Sands is pretty low in quality (other than context and graphics), and aside from being abandoned, it's short, too little content. I saw it was mentionned a lot when I was searching for something like Desert Stalker while waiting for the update, tried it (and kind of liked it if I didn't try to compare with DS) but was disappointed with the lack of content. Unfortunately, I found no game to come close to Desert Stalker's quality (kinks, graphics and context/genre)... I would love someone to tell me I'm wrong...
