According to ESRB, this game features: Cartoon Violence
Parents have nothing to worry about here. Mega Man's violence is the lasers-and-lights stuff of Saturday morning cartoons. If a robot does happen to lose its "internal organs," they're just bolts and screws. There's no sexual content or bad language whatsoever.
Younger gamers will probably be less daunted by Mega Man than I was as a kid, thanks to the Anniversary Collection's "Easy" and hint modes.
Deaf and Hard of Hearing gamers will find that most of the Mega Man games have no significant auditory cues; however, they will miss the Robot Masters' spoken phrases in Mega Man 8 which warn players of their attacks. Nor do the cutscenes in Mega Man 8 have subtitles. But most damning of all, the unlockable interviews on the disc have no subtitles, either.
