When I play a game, I keep trying, then at some time I get stuck, and I ask on the forums. I always wonder how the people who answered knew how to do that part, even though they are not authors. The point is, what are the ways people use to complete a game? I also ask this to myself when I look at walkthroughs. Do other people wonder this? Is it that I'm not looking at enough walkthroughs to strategically complete a game? Or do I not really understand the strategy in the hints?
