The height of new game glory for me were the old school huge boxes PC games came in. It wasn't uncommon to get a thick manual with wonderful art, sometimes spiral bound, maps, other neat add-ins. Even console games had nice manuals with useful information you may not otherwise know. I miss that stuff.
I wrote a similar reply to a higher comment without seeing yours, and I completely agree - I miss it.
I was a bit younger in the 90s and half the magic of the ride home was reading the manual so you could hit the ground running when you installed it/put the cartridge in/loaded the tape.
Remember how the front of the World of Warcraft would open up to all that awesome art? That and the manual kept me entertained while all the disks installed.
