The Japanese release of zombie adventure Dead Rising was hidden away in Tokyo retail stores due to its eighteen-and-over rating, reports Game-Science:
Previously, a similar adults-only rating was applied to several Japanese games, but the change in ratings system was accompanied by a new law making it illegal to sell the "Z" games to minors, says Game-Science.
This is exactly what free-speech advocates mean when we say that making sales of violent video games to kids illegal will have a "chilling effect" on creative output. Capcom heavily censored the Japanese release of the game, but it seems to have been all for naught, as it still received a Z-rating – and has subsequently been all but hidden away in Japanese stores.
What happens now? It's highly likely that no other games publisher will want to repeat this scenario – they want their games actually displayed on shelves, after all. So they'll probably engage in heavy self-censorship to make sure their games don't get slapped with the Z-rating kiss of death.
And it's not even as if Dead Rising is that grotesque of a game. Its brand of campy, cartoonish, over-the-top dismemberings and beheadings were more along the lines of a comedy slasher flick, which remain entirely legal to be viewed by (and in many cases the near-exclusive province of) minors.
Game-Science calls it "unnerving." That's a heavy understatement.
