What is the symbol for video gaming as a whole?

Space Invaders Alien

Frying pan with scrambled eggs!

A clock thrown into a trashcan.

Mario. Hands down.

Red Bull.

Atari controller. So iconic.

Perhaps a SNES controller, or just the D-pad.
Since every game has a d-pad.

Maybe Mario with a d-pad backdrop?

This

Bloodshot eyes.

A simplified, stylized graphic of an oversized thumb with a red glow emanating from it in the “thumbs up” position.

Original nintendo system. NES, definately. As a child of the 80’s, that’s it for me.

How about an arcade machine? A coin-op.

A joystick and cord plugged in to the side of the head. Or a hand melted to the joystick controller.

Someone drooling surrounded by energy drinks.

I speak from experience In their pockets i’m owned.

Ive been trying to figure this out for a long time for a tattoo idea, but its been hard.

I think I’d pick the D-pad, like @Nullo and @johnpowell mentioned.
Computer gaming’s symbol is of course, WASD.
