I'm wondering, that since Jenova (the editor, not the monster :P ) can change your in-game location, maybe it's possible toa djust it so you are not stuck in the wall and see where it leads.
Afterall, if it IS unfinished, it may help us learn about how hey are made, since a work in progress might not be as hard to pull apart
And another one. Even watched that sceane in the truck to Nibelheim with Cliud and Sephiroth that was never in the game?
Sephiroth explais how materia was made(much diffrent to when he explained it at the Mako fountain) and after the game crashed tot he desktop.
Weird :)
