I think its just a nice perk since instruction booklets are so rare nowadays. So when one is actually included it feels like extra effort was put in. I know I only ever read them when they had some kind of gimmick like the ones you said.

Also for anyone who hasn't read it yet/doesn't have the game yet, aside from the basic instructions, there's also little bios on each marriageable candidate, and a little comic strip on the last few pages about what you can do in Mineral Town that's kind of cute.
