With each game I purchase, the instruction manuals are getting thinner and thinner, and it kinda makes me sad because I love reading instruction manuals.
I remember when I wasn't allowed to play games as a kid, I would just read through instruction manuals to learn more about games, back then games weren't so big on tutorial levels and the manuals had everything, characters, background stories, and hints etc etc, I read the crap out of Resident Evil 3's manual because I thought it would somehow make me better prepared against Nemesis . Now days they're just a couple of pages outlining basic controls.
My favourite manual of all time is from Uncharted: Drake's Fourtune, it looks exactly like Sir Francis Drake's journal in the game, I would flip through it during a cutscene and pretending that I was looking at the same journal as Nate .
The paper manuals are probably going to be completely removed at some point, and it will be a sad day for me, just another thing to be taken away from the 'good old days'.
