The story centers around Shinra Inc., a powerful corporation that uses facilities called reactors to suck mako, the planet's life, out from the earth to use for their own purposes.
AVALANCHE, a resistance faction very much in opposition of Shinra's actions, sets out to destroy these reactors and bring an end to Shinra's reign.
Things escalate and become much more complicated after the appearance of Aerith, a cheerful young woman who is much more than she seems, and the return of a ghost from the past, the ultimate SOLDIER, Sephiroth.
Final Fantasy VII is a tale of a man's quest to settle his past and an epic struggle for the planet's life.
It is highly recommended to any fan of rpgs.
