I just noticed that the manual file skips from page 13 to page 24. There's supposed to be information there that is missing, like the "hints section" which in the same manual it is specified to be in page 19. How can I get the full manual? That's bad GOG :(

I checked the manual at sierrahelp.com and pages 13-23 contain just a lot of addresses and phone numbers at Sierra. The hints section you mention is just phone numbers you can call for hints and information on how much it costs you. There's also a money-back guarantee for a month in return for telling why you didn't like the game, and some warranty information. All of it outdated, in all likelihood.

I can see why they wouldn't want to ship this information. Still, I don't like being sold incomplete goods. Would be better to just include a note saying the manual is reproduced as it was printed at the time of release, and that the reader should understand that any services offered at the time have probably long since ceased to exist.

Oh, thank you. I guess I wouldn't be able to pass a prank call to those old number

Or a note explaining why the sections were removed at the very least. Adventure gamers in general are slightly more likely to pay attention to small details like page numbers and notice when they suddenly skip ahead.
