During the development of Metal Gear Solid 2: Sons of Liberty, Hideo Kojima came up with a Grand Game Plan for the sequel to Metal Gear Solid and how it would be utilized on the PlayStation 2. The Grand Game Plan was included in The Document of Metal Gear Solid 2, although only in the original Japanese text.
In July 2006, Marc Laidlaw of Junker HQ released an English translation of the Grand Game Plan: MGS2gameplan.pdf
Excellent!
This is a great example of a pre production GD’s vision. There are many game elements summarized in a compact way.
From plot and game mechanics to thoughts on design, development plan.
Oh, also this document helps understand MGS better :j
