I enjoy playing a game blind and finding all the secrets myself. It may takes much longer to complete but I don't care, I'd rather play less game by my own than playing more games spoiled with walkthrough. That said I'm not totally against using walkthrough and when I got really stuck and it stops being fun I just google the solution for that particular puzzle, but after that I continue to go on blind.

Not to mention I'm a student and don't have much money to spend, so by taking my time to finish a game I get much more worth from my purchase.
