I've been gaming for as long as I was strong enough to hold a controller.
My father had an NES, which he bought a year before I was born. I'm not sure which game was the first I ever played, but it was either Super Mario Bros 1 or 3, Megaman 1 or Ice Climber.
Early '80s. My mom worked at a bowling alley, and I'd get free credits in the arcade from the people who worked there.
Donkey Kong, Pac-Man, Zaxxon, Bag Man were favorites.
We got an Atari 2600 later. Our neighbors had a Colecovision. Even when I was a kid, I'd drool over the better graphics on Coleco and in the arcades. :)
