Like China, did they survive the initial attacks? Or is China a similar wasteland.
What about other countries, did they suffer also?
Would be good fun to find a transport device to take you places Make the game seem larger
I can answer that.
The world over has gone to hell. After China and America launched their nukes, the other countries did too, mostly in a panic for self defense. The rest of the world is in a similar state to the continental US.
I really don't think New Vegas would have worked as a Fallout 3 expansion, and don't make me bring up the L4D2 argument again. The player character is different from the one in Fallout 3. You're a courier, and you weren't even born in a Vault. It doesn't even take place in the same area.
