So basically if something gets a cero rating of Z it's basically hidden behind the counter, not advertised in stores and what not. A load of X360 games have fallen foul of this (Dead Rising had an almost anonymous launch here in stores), and a load of Xbox games got post-release rerated from Cero 18 to Cero Z.
Ninja Gaiden / NG Black being one such game.
So someone has to explain to me HOW THE FUCK Ninja Gaiden Sigma snuck in with a FUCKING D rating?!
I know it seems trivial but this makes a huge difference to how the game can be displayed in stores etc.
Conspiracy total. All of Japan running scared from the Xjuggernaut total.
