I highly recommend the book 500 Years Later: An Oral History of Final Fantasy VII. It's Matt Leone's article, but expanded to book length (240 pages). I received it as a Christmas present when it came out from my parents. Read the entire book in a day. Reading the book was a super nostalgic experience for me since my parents purchased the original PSX game for me back in 1998 around Christmas that year. It was awesome reading all that went into one of my favorite games of all time.
