Do you believe that watching videos on YouTube or on other videos networks can be helpful in order to complete a game? Or do you just have fun while you're watching them?
Personally, I enjoy watching videos because it is a very funny activity. I remember that when I used to play Seafight ( an online game ), I was addicted to these kind of videos. They can teach you new techniques and you can benefit from them in many domains.

I would have to agree as well, you have to learn some how, and if you are not that accomplished at the game, and you want to learn fast then watching videos is the best way to get experience and make yourself better. I hate those videos that show how people to glitch, I think its not fair on other people, when they use them in a game.
