One of the best guides out there
The Super Mario 64 Complete Clear Guide Book may be one of the most well-known and sought-after guide books out there. This guide, released in Japan alongside the launch of Super Mario 64, details the game in painstaking detail, and with unbelievable style and flair.
As you can see above, this guide book put together actual dioramas of stages, clay figurines for characters, and so much more. This is as much a coffee table art book as it is a Super Mario 64 guide!
While the guide itself has long been out of print, and physical copies are incredibly hard to find, the Internet Archive has come to the rescue. You can now flip through every page of this guide virtually, and enjoy the wonders within at your own leisure. Just hit up this link to have a look!
