This is still a very clear memory in my mind. I not only remember the first video game I played, but when and where I played it. The game: Super Mario World, the age 3-4 years old. I was at a pool party with my parents (obviously), and very, very bored. They stuck me in a room with one of the children. We had never met before, so instead of talking he fired up his SNES. The second I touched the controller a radical transformation took place. I no longer was just a boy: I was a gamer. And that my friends is what we call history!
I don't know what the first game I ever played was. Probably pong or a variant as we had cheap TV games back in the 70's. I know a friend had an Atari VHS but I cannot remember playing it.
First game I remember playing a great deal with WIzardry - Knight of Diamonds, or perhaps the original Castle Wolfenstein (not the 3d one) on an Apple iie in early 80's I guess - would have had to be as I didn't see a computer until 1982.
