Oh wow, this looks really nice! I haven't read it obbiously, but I might argue that it's better that it's "looking backwards without connecting that past much into the future," since it's probably aged better as a book.
It is really interesting that it was written in 2001, though. That would be like writing a book now that interviews people that worked on PS2 and Xbox games. They're not really in the realm of vintage yet, they're just old. So yeah, I can see why the people being interviewed would be like, "wow, you guys actually care about this old stuff?" It seems like an interesting read!
