What is the shortest game of in the whole world

Since the highest chess piece in the world is 20 feet tall ... And it took time to move that piece.
Then the shortest piece that was moved during a game is an online chess piece. It's flat, so it cannot get any shorter. :)

But if short in temp, then the pawn stepping short rather than long.

The 2 move help mate is a short game.
Resigning before it starts is short too.
No show, with only one player showing up and winning immediately becasue the player arrives late.
Or a 1 second game.

Since the subject question is in the off topic section, then the shortest game is not chess ...
