If your life revolves around video games, by definition you're a shallow person.
Mayhap you need to generalise that a bit more. Video games per se aren't all that bad. I've struck up a few conversations with younger women about video games.
Say instead that "if your life revolves around only one particular activity, by definition, you're a shallow person".
To which I certainly agree. Be it video games, shopping, facebook, football, clothing, gym, programming, or clubbing, anything can be taken to excess. Also, it's fun to try something different every so often. My recent craze is slacklining. Great fun, and I genuinely believe most people are capable of it with practice. Age is not an excuse.
