This has perked my interest.

What kind of state is the world in? Is it all deserts like Mad Max or is it more like Fallout where buildings remain albeit overgrown with vegetation and people trying to start fresh?

Fantastic! At this rate, we'll have enough people to start the game in no time! I'm not being sarcastic about that either. Little over 99% of the world has either too little water, or too much, as such, the terrain varies wildly, and due to the lingering effects of the apocalypse, it tends to be quite inhospitable to life in general, from barren wasteland, and polluted hellscapes, all the way to acidic swamps and mutated jungles, and everything in between. 

Fertile, unpolluted, or "clean" land is highly valuable, sought after, and fought over, changing hands frequently, often within mere months. The mindset of people varies from faction to faction, and even settlement to settlement, though there exists a general idea that those still living are heirs to what's left of the earth. The concept has spurred what could be described as a Second Manifest Destiny, and there's a general sense of conquest, expansion, and settlement. Of course, the world is still very much untamed, and the mutant tribes and pseudo-human clans don't tend to take kindly to outsiders.
