Video games came with its own advantages and disadvantages just like all other inventions.
Video games can make some people mad, some don't concentrate about their lives, it has made some completely lazy and they can't take of themselves since they can't face reality.
Video games has also made people change their mindset, there are some games that have pushed people into killing because the gamer wanted to live the video games life, one thing I will like to point out is that gamers who acts all crazy have gone too far. Playing video games and then immitating it is a matter of mind set, there are other people around who play video games a lot but don't start acting all crazy, this set of people but still they maintain their composure. People who have gone crazy because of video games do not listen their consciousness.
