I love gaming, it doesn't rule my life and isn't my hobby, but i do enjoy sitting down and spend half an hour to an hour on GTA, Call Of Duty Assassins Creed or Skyrim. On the other hand many people play games all day, and most of the night. If you aren't a gamer then you may not understand the fascination but for those who are they do understand. You may look at a gamer and think they have no life, but they aren't committing crimes are they?
Playing computer games or video games is actually good for you, not to much obviously but it can help your brain function faster, not forgetting having faster reaction speeds. There is more to it.
