Well I would think USA and Europe are pretty much dust along with Asia but us cool guys over here in Africa? Well we just partied on. LOL
It never ceases to amaze me how everyone seems to see the world as America and Europe, there is a lot more to the world than just that pull out an atlas and have a look you may be surprised.
After the USSR fell apart, some of their declassified documents showed that in the event of an all out nuclear war they would nuke many uninvolved cities all over the world. That was simply to keep everyone as wounded as their nation would have been. Never heard if the US would have done that, but I tend to think we would have. Since the world of Fallout is pretty much a worst case scenario, there's a good chance many targets in Africa would have been hit twice. Once by each side!
Also, don't forget, not being hit by the full nuke exchange wouldn't mean everything was A-OK. There's a nuclear winter to deal with. A couple years of nothing but winter. Plus, Africa doesn't have a very good track record with respect to the longevity of social systems and nations. I think Africa would be healthier than much of the rest of the world... but because of long standing bad blood and radiation, probably not much better off than it would have been in 2077.
Wandering kind off topic, African history is pretty darn interesting. I took a semester of it in school and wish I could have taken part II. A topic worth blowing one of your xmas gift cards on!
