Would it be so ridiculous to think that a person could be addicted to a game, like one could be addicted to drugs or alcohol? I believe game addiction does exist and can be detrimental to someones life. Affecting work, school, friends, family, etc. The amount of time that is spent on typical game play is astonishing. This article from webMD goes into more detail. http://www.webmd.com/mental-health/features/video-game-addiction-no-fun?page=2
I think like any addiction one has to pay attention to the warning signs and of course have set time limits for game play, even for yourself. Gaming as we know it can and is fun, but everything in moderation! Too much of one thing can never be good.
