The obsessed fans over at MetalGearSolid.org have posted an English translation of the design document for Metal Gear Solid 2. The document was previously only available to Japanese fans who purchased a documentary about the making of the game.
Among the revelations in the document:
MGS2 was originally going to be called "Metal Gear Solid III," for extra confusion and symbolism.
Raiden was designed partially as "a character in which women can more easily empathize."
A consumer package containing both MGS and MGS2 was considered.
The full document also includes insights into the symbolism of the game's confusing story, and some thoughts on the nature of sequels in general. Definitely worth a read for anyone with an interest in this seminal game.
