CheatCC says - "Think about games you have played that came with a “tutorial” mode. How many of you actually ended up completing it? If you are a completionist you might have, but many gamers simply look over tutorial modes and try to learn by doing. This doesn’t always work out, however, as many games, like fighting games or shooters, require a lot of skill and knowledge for competency. Anyone who has asked, “How do I block?” or “How do I throw grenades?” hasn’t played the tutorial mode. Shame on them!"
