I love the question of "what was your first video game" because I absolutely don't remember even slightly.
It's a fun guessing game I get to play with myself and I can pretty much state as fact I'll be wrong.
I only have a real answer for this because when growing up my older brother was the only one out of the three of who played games. I would just watch. But then he bought me Ocarina of Time and said I’d love it. It was my first game, and he was right. I knew nothing about Zelda before that.
