Oh my god, this place makes me feel older and older!
I'm 30 in a few months, and I started playing when I was 2 - I know that sounds young, but we moved into a pub and had a Pacman / Headon cocktail cabinet with as many free credits as I wanted! Every couple of months we'd have a new one delivered, so I was fortunate to have a cabinet with the latest arcade games for most of my childhood!
