One thing that struck me with Fallout is how the majority of the people you meet can speak fluent English. I was watching Threads the other day and it puts forward that even within one generation the language has degraded to be much simpler and mono-syllabic for the most part. Of course many people would survive who knew the language but as they're more concerned with survival as oppose to education it'd make sense that the post-apoc children wouldn't be very articulate. Do you really think that the English language would survive in it's current form after a Nuclear War? In reality would the time between when the bombs dropped to when the Vault Dweller emerges be too great for the English language to be sustained? Of course some would be educated, I have no doubt that some "schools" would still be run, but the people capable of articulate speech would be by far in the minority wouldn't they?
