It seems that in order to address the question, you'd need either first-hand experience of all the intervening periods in question, or perhaps a huge stack of multi-sourced anecdotal evidence from someone(s) who had, or perhaps both of those.
I love reading history, but I don't have the wherewithal or the skill to do the research necessary to write it. I'm curious about the periods that I missed entirely (2nd edition, 4th edition), but I wouldn't attempt to acquire them or their ancillary materials in order to discern how they're different from the ones of which I have direct experience.
And I feel like an outsider pretty much everywhere, but I'm curious about communities themselves, so I tend to poke about the periphery.
