As a child, I made a siren in QBASIC. Very proud, 2000 lines of code.

My sister’s boyfriend then introduced me to the concept of FOR loops. 6 lines of code.

Anything that can be made playable in the terminal like so is gods’ own work … but someone needs to teach that poor coder about subroutines, and the various gameplay engines(AI/CPU opponents, and move validation) that exist already.

Hell, the UI/UX work may be in place already, but some wheels can be rewarding to reinvent, even if only to learn them from the ground up.

On the upside, if he’s finished with this he has literally solved chess.

On the downside, the heat death of the universe will probably happen before he’s able to finish this.
