Personally, I don't think you can become addicted to gaming. I think people use addiction too often as a scapegoat for their own lack of self control. As long as the rest of your life is in order, you're doing the right things, functioning in society and enjoy a night out every once in a while, you're not addicted, or even engaged in unhealthy behavior. The fact that you're getting out to meet family is another sign, after all, if games were so important you needed them on the level addiction implies, you'd be a hermit.
