I just heard the news about new game plus and I gotta say I am THRILLED. This is what I've always wanted, to re-experience the story, in addition to a new way to level side jobs. With the ability to start at specific base patches, I have to wonder, could we expect a "reborn" 1.0 someday? I would love to play the 1.0 storyline, as I never had the chance to before the Calamity.
I dont think it would be terribly difficult, keep the basic weapon system the same as 2.0+, divide the zones like we have them now, but add the quests and story from back then, I dont know if all of that data was saved prior to servers shutting down, if they were I'd imagine it would be all the easier.
