I'll share a childhood story as well.
Somewhere between '93 and '95 my father took me abroad to Germany and we visited a gaming venue. It was packed with typical arcade machines, games where you sit in a cart holding a pistol and you shoot things on the screen while cart was moving all over the place simulating bumpy ride, etc.
But the highlight was a full 3D experience shooter.
You got yourself into a tiny ring, 3D headset and a single puck hold in hand. Rotate the puck and you move. Push the button and you shoot. Look around with your head. Most memorable part - you could duck to avoid shots!
Game itself, as I remember it, was full wireframe, akin to Q3DM17 (the longest yard) minus jump pads, but the layout was kind of similar. Player was holding a dart gun - you had a single shot and you had to wait until the projectile decayed or connected with other player.
I'm not entirely sure if the game was multiplayer or not.
I often come back to that memory because shortly after within that time frame my father took me to a computer fair where I had the opportunity to play doom/hexen with VFX1 (or whatever it was called) and it was supposed to revolutionize the world the way AI is suppose to do it now.
Then there was a P5 glove with jaw dropping demo videos of endless possibilities of 3D modelling with your hands, navigating a mech like you were actually inside, etc.
It never came.
