I recently picked up a copy of this from a retro game store while on vacation. The box was covered in dust and slightly damaged on the corners. To my surprise everything inside was in mint condition. Simulators obviously have a higher standard of documentation, but it really made me miss game manuals in general.
Tunic, a game released last year, contained an in game manual in the style of older games. I personally found it legitimately useful, and fangamer recently released a hardcover version that is now out of stock.
