As I thought, most of the extras are engaging, but not really memorable. Instead of a making-of-the-game feature, there's just a load of developer (and translator) interviews, and a half-hour “History of Final Fantasy” overview that does little more than run down the plot of each game and point out the many incarnations of Cid and the Chocobos. Unsurprisingly, it doesn't mention the god-awful Final Fantasy Mystic Quest or the planned Famicom version of Final Fantasy IV. A few interesting details pop up, but if you're a big enough Final Fantasy nerd to pay extra for a bonus disc, you're probably a big enough Final Fantasy nerd to know everything that disc could possibly tell you.
However, it's nice to confirm that Akihiko Yoshida doesn't walk around in the same medieval bondage outfits he uses in his character art. He just looks like he belongs in one of Japan's few Weezer cover bands, a proper calling for anyone.
