In truth, I would say yes, they often have a not-insignificant impact on my life. But when talking about video games with IRL people... I often find myself trying to hide that fact, and claim it as no more than a passtime.
Maybe it's because gaming, compared to many other hobbies, is "unproductive" or thought of as just toys. Maybe that's because it's a relatively newer form of media, compared to movies or television. I can't say for certain.
I have no problem admitting to myself or close friends that I'm a gamer... But with anyone else, I don't find myself so open to talk about what is pretty much a primary hobby of mine. I'm not sure why that is.
