I am not sure if it would be described as a "video game", but I did play one of the very first "computer" games: a sort of digital Squash played by a vertical line to represnet a racket, bouncing a large dot off the side of the TV screen. (The games unit was plugged into the TV's ariel socket.)

My first PC was an Amstrad PCW9512, primarily a word-processor with a monochrome display; and surprisingly perhaps the auxiliary programmes bundled with it was a chess game that represented the board and pieces in 3D!

Othar than those..... I have never played a computer game since.

Pong at home.
Space Invaders in an arcade.

edit: I'm second guessing myself now, was there a game before SI?
'Asteroid' maybe; there was a car racing game where the car was a real model car and the road was illuminated from behind - or am I imagining this?
Old Guys and girls anybody?

Super Mario RPG: Legend of the Seven Stars for SNES. It's still my favorite game to this day.

Number muncher. It was a math game for kids i played in like 3rd grade on an old school mac computer. Back when everything was floppy disks and pixelated graphics.

Something on Atari 5200 but I can't be sure which was actually the first. Maybe Super Breakout, Space Invaders, or Pac Man.
