So my question to you is who do you feel would be the biggest face in gaming, besides Mario of course. I am not including a generic "Call of Duty" person on this list, only characters that gamers and non-gamers alike would recognize. I'm saying Sonic would be my choice of most recognizable. Even though the series has died off,  he's still an extremely known character that dashes across the minds of children and adults every now and then, and  apicture would certainly be known.

Francis York Morgan.

It's Pacman. This is known.

Probably Sonic.

Pac-Man. Been around longer than most, very simple design, instantly recognizable.

Green Mario 

Sanic.

Pikachu or pacman

Probably Pac Man because the non-3D model is just basically a circle. Very hard to get confused with other game characters.

I would have said Pikachu, but many young kids like to deny that they like Pokemon...

Maybe Pacman, Sonic, or Pikachu?
