I'm 44 years old, and my first-ever PC was my dad's hand-me-down ZX Spectrum. I'm not sure of the first game I played, but the first one I remember is Horace Goes Skiing. The humble Speccy kicked off the hobby of a lifetime: my habits may have changed over the years, but gaming has been a constant joy in my life.
So much so that in my 20s I became a games journalist. I've worked for almost every outlet you've heard of over the last 20 years, as well as writing a full history of the medium, and I never tire of learning new things about games. Now that I have children, I delight in watching them explore and fall in love with these wonderful virtual worlds.
