Ok, so I used to enjoy reading rumors about FFVII. How to bring Aeris back, Onyx Weapon, Fighting the meteor, all that kind of stuff. Back in the day though, I remember reading a "mystery" of sorts. It was about those two red shinra soldiers who stand at the base of the tower in sector seven, and are blocking off a very noticeable path.
Now, back then I just believed what I read and assumed it was a part of the game that was taken out due to time constraints. But while playing through the game again it suddenly hit me... That path is probably what leads to Sector 6.
It makes perfect sense. I mean, there are no pathways that take you directly to sector 6 from Sector 7, yet in the playground area, you can see a very noticeable door, so there clearly HAS to be a pathway leading to it. Not only that, but that's also the general direction that you go sailing through the air in when you're escaping Sector 7.
I can't believe it took me roughly 13 years to realize this... I feel stupid now.
