Would be cool if you couldn't destroy deserts. Otherwise, again, you end up with one desert city that produces units and everything else is plains. Neat idea! But it seems like it'd be micromanagement hell... also, these nomads would have to be unrealistically powerful (like huge resources) in order to compete with simply transforming everything to plains. I like the nomad camp, esp. when I wrote about the spring oases like 8 posts up But yea... doesn't have to be Oasis, just some sort of super improvement with spacing requirements. I'm not sure about the living desert though.. the idea with deep jungles or forests is that they can actually provide for survival in the form of food and building materials etc. Deserts generally don't... and deep deserts should be even more barren than normal ones.
