Final fantasy VII...the game plzzz?

No other movies on that story but there is a psp game called Crisis Core that deals with Zach and Cloud. It really helps with it overall, I don't recall to much about the game but I think Zach was the soldier cloud thought he was. In the flash back parts where you play as cloud, that was really all Zach. The game gives a good enough explanation of it all and if you have a ps3 you can get it on there for fairly cheap. Other then that you could try to find the old ps1 game online at places like ebay and then use a playstation emulator to play it.
