I personally miss reading manuals (or at least skimming them if they're big) before playing games. I guess it feels too much like study/work for it to have a market nowadays; last physical games I've bought had basically the same info as in-game help.

When I was a kid my grandparents would sometimes get me a computer game when I visited. But they had no computer! This meant I could spend the weekend poring over the manual in anticipation.
My favorite was SimEarth (200+ pages and spiral bound as I recall!) but TIE Fighter was great too, since the manual was in the form of a novella.
Back in the days I and others made an end of junior high school year project on military planes and we had a monitor playing clips of F-16 Falcon, F-29 Retaliator and Fighter Bomber. I did however use the F-19 Stealth Fighter game manual as an inspiration to write texts on the improvised stand we were using. We also had some model kits on display.
