Who uses them? When you get stuck in a game, do you persevere and try to work it out yourself or do you go reaching for the game guide or log on to a site like GameFAQs? Or, do you flat out cheat your way to victory?
My cousin and I used to blast our way through Doom II using cheats but the experience got pretty boring after a while. To that end, I finally played Doom II from start to finish sometime last year without using a single cheat and it felt pretty rewarding, or at least as rewarding as a video game can feel. These days I tend to steer clear of cheats when I'm trying to finish a game but if I'm just having some fun I might use them while I'm mucking around with the game.
If I'm stuck in a game like GTA, I might reach for the guides to see if there's an easier way of completing a mission or to get some tips so I don't make it any harder than it needs to be. In some cases, I'll check the guide to see how close I was to finishing a mission that I've failed so that I can better prepare myself on the next attempt. I've often consulted walkthroughs with the old LucasArts adventure games as well.
