I remember my manual for Falcon 3.0 was the size of a novel.

As far as manuals being included. I remember GameCube games having manuals.

I remember those, too. I had to call up my friend to turn his code wheel whenever I wanted to play my pirated copy.

I bought the Collectors Edition of Stardew Valley and it came with a map, mini-guidebook, and soundtrack. It's nice to have one manual with one of my Black Friday game purchases...
