What was the first videogame that you remember playing?

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.
