I don't know if I need a Final Fantasy 7 game in which you can enter even more buildings and do even more stuff; I've already wasted enough hours of my life on the core game as it was
IMO the game was pretty well balanced in what it allowed you to do and what it blocked you from doing. There is such a thing as too much freedom, then you get sandbox problems of people being lost and not understanding how to have fun.
Respect to this person that he managed to do it of course.
