This is a documentation of the production of the video games Xenogears and Xenosaga I, II and III. This was all produced by the user A.C. and I am eternally grateful to him for this titanic work that must never be lost. 

Edit:
Since A.C. has returned, he has requested that archives of his materia be removed.  I have substituted the links previously entered with links to his official material.
