My first guide was for Pokemon Gold/Silver, though my parents got that for me because I was a good girl for granny (and they gave me Silver just before they left). My next one was Link To The Past (GBA), though I got it because I was genuinely stuck at the 2nd dungeon (didn't catch on to how sometimes pushing boxes triggers doors to open) and our internet wasn't stable. Plus, it was also my first owned Zelda game so I was still SQUEEing. My FF7 came with guide, so I got it. Was very useful too since I didn't need to bounce back and forth between the tv and computer.
Today with internet guides so easy to find and understand, I don't have too much business to grab one. Sometimes pulling up a video or fan guide is even MORE useful than an official guide. Even before that I would USUALLY find out what to do in a game. If found a cheapie, even to a game I might know inside/out, I might get it for collecting purposes or if there are any interesting/useful tidbits. Someone I know was giving away their Jak 2 guide and I was salivating for it (Jak 2 being a game I both love and dread). I didn't get it though
