After seeing a video that Jane McGonigal I realize that actually, games can help us a lot.But many might thing that really games cannot help us.Gamers spend up to 3 billion hours a week playing games and 21 billion of the people that are games are actually helping problems like hunger.Evidence found that many gamers think that they are better at playing games that who they are in real life because you get to know a person by playing a game than meeting them as usual.Many gamers spend 10,000 hours gaming at the age of 21 then why not make the world more like a game that it can give better feedback.Afterall, I think that games can help us with the world's problems by playing games.
