Pacman's ferocity is 61.7% at the ESRB examination

Pac-Man who certainly can also eat enemies may be a bizarre creature of a mystery, but it seems that it was not such a dangerous game.Understanding the 62% Violent Pac-Man

The judgment of ESRB's ferocity is decided by 90 minutes, depending on how long it is performing violent behavior towards other characters. So Super Mario Brothers' ferocity is 41.3%, Legend of Zelda is 68.4%, and Gallaga of shooting game is 100% ferocious.
However, it seems that these are in an incomprehensible state that rating is classified as E (game suitable for all ages).

It seems that Kimberly Thompson of Harvard University gave an opinion to the US Senate whether it was strange.
