Like a lot of people here I tend to only use the walkthroughs if I'm truly stuck, and it also depends the type of game. If it's a puzzle game or a puzzle in a game I have a lot more fun consulting another mind (whoever's around) than going to an FAQ, but if it's something in an RPG like "I can't figure out who to talk to" or I've tried a boss battle 13 times to no avail I have no shame in checking an FAQ. I'm not hardcore enough to hide the fact that I'm simply sucking at a certain section of the game

.
I remember Dad used to buy me the walkthroughs to RPGs he bought me for christmas or whatever, and I always TRIED to avoid them but having the guide right there tempted me to look at it a lot more for some reason.
Also, if I'm playing an RPG a second time for completion I'll definitely use a guide so I don't miss anything.
Jam it back in, in the dark.
