Well when we started gaming, the internet was in its infancy, and there weren't dozens of gamefaqs for every game, or video walkthroughs, or lets plays everywhere. So the resources for information are there, and so we use them. It's not that surprising. In the old days, if you got stuck, you were just stuck until you either figured it out after hours or days of fiddling, or you just quit the game (maybe forever). When I first played Full Throttle, for instance, I couldn't figure out for the life of me how to get out of the "junkyard and fuel tower" area. So after a few days of frustration, I just put the game down, and didn't come back to it for over a year, at which point I actually was able to figure it out and progress.
Now, unless a game is absolutely brand-spankin-new, there's no reason to have to give up a game in frustration, unless it's badly designed or horrifically hard or something.
I've recently been playing Divinity 2 for the first time, and I immediately went out and found some guides for it. Mostly for information about the alchemy and crafting systems, and for info on how to find all of the hidden items everywhere... but info about alternate solutions for quests was nice too. I think it enhanced my enjoyment of the game, because I wasn't going in completely blind and missing opportunities to find things, or accidentally using up extremely rare ingredients for fart potions etc. (I've been avoiding quest spoilers, though.)
