We make sure that nothing of the story or any important events get changed, so it's just more of a prettying up of day 1. Since that was the section that i did for the initial release, without much of a plan of where to take it, and when i was just doing it as a little bit of a project in my month off. I just don't think it holds up and so by now everything but the Rajeeyah & Arthur section have been overhauled.
It's absolutely not needed to go back since as I said, the essence of the scene is still the same, but if you thought that particular scene was one you liked, then it now should be even better! :D
