My first video game.... well, It would be a tie between Coleco Vision, Atari, and NES games.
I really can't remember what I played first, but when I was real young, my parents and I played those kind of games the most.
My mother was, (and is still) addicted to Dr. Mario, and My father was addicted to Adventure, despite how short and blocky it is.
(HECK, the "dragons" look like DUCKS)
But when I was little, it was either NES, or Atari, Or Coleco Vision. That was it.
The first game I remember 100% fully enjoying, was Spyro The Dragon. (for the original Playstation)
But, it was not the first one I've played.
