I use walkthroughs, yes. But not for games i truly play to enjoy the fullness of it. Mass effect for example, never looked at a guide for it. Assassin's creed? Yes i did, mainly cause i was playing for the story. Also if someone spoils a game for me i might as well use a walkthrough, since it was already spoiled. I may feel a bit guilty, sure but it's my enjoyment in the end, i choose how to experience my fun, if i may use a guiding hand for it, so what?
