I'm perfectly ok with 1.0 being this time in history that I can only open up an ancient tome and read about (or look up videos on youtube). 1.0 is like a cult classic that you just don't touch despite having better technology; it can't capture the essence of 1.0 that now exists as nostalgia for the players that went through it.

If they were going to put in the effort to have us live through another part of Eorzea's history, I would rather them go back further. Way back. Prior to the 3rd calamity and in Meracydia during the days the real Bahamut was alive. If there is anything I would love to see expanded upon, it would involve Midgarsormr and the first brood and I highly doubt I am the only one.
