Huh. I feel like a Ms Pac-Man/Galaga multigame in the corner of a laundromat or restaurant is really the most common way for anyone to run into Pac-Man now, and yet here's Namco trying to retcon her out of existence.
I think the omnipresence of Ms. Pac-Man is a US only thing, I'm not sure the cabinet was even released elsewhere. So the most common for you and me, but not most people.
