This isn't a game, appears to be a movie based at the end of FFVII, witch I have yet to get off the 1st disk before my freind took his PS1 back. Just thought you guys wanted to see it, and here's the site with the info:

I don't know much about the movie, considerign I don't feel like reading anything that involves thereotical-ness... someone may understand that, lol.
Don't shoot me if you knew of this.
