In 1993, Nintendo of Japan published an official Star Fox guidebook that contained the game’s little-known original backstory, along with:
• Two unique characters that never appeared in anything else • Original illustrations by Benimaru Itoh, whose Star Fox and Metroid comic serializations appeared in Nintendo Power • A canon that was later scrapped with the series reboot of Star Fox 64
In December of 2011, Nintendo released an official Zelda artbook called Hyrule Historia! In addition to revealing the official timeline for the Zelda games, the book also contains never-before-released concept art!
Take a look at these newly-translated concept art pages from Adventure of Link, Link’s Awakening, and A Link to the Past!:
