Cambrey: Maybe they are aware of those games, just didn't care for them.
Tokyo_Bunny_8990: I do think its a big part a matter of taste and another the strict rating system blocking many notable western games.
The notable games that seem to be missing are Witcher 3, GTA, Red Dead Redemption 2, Halo, Half Life, Mass Effect, Batman Arkham, and God of War.
Alot of these games are rated Z which is the highest rating of 18 or above (Witcher 3, RDR2, God of War, GTA, CoD, TLoU, Ass Creed. In comparison, even Resident Evil, Yakuza, MGS, and Evil Within has a D rating. That already limits their accessibility compared to other games like Monster Hunt (C) or Zelda (B).
FPS games like Half Life and Halo also arnt as popular in Japan compared to the US, hence their lack of their appearance here.
To what degree do maturity ratings affect the accessibility/sales of games in Japan? In the US, M-rated (2nd highest rating) are sold alongside E-rated (the lowest) at major retailers. Some stores may have policies to that prevent minors from buying M-rated games themselves, but it doesn't hurt sales much since an older person can easily buy a game on their behalf. The only rating publishers have to worry about is AO (which is very rare) if they desire mainstream success.
I'm curious about the discrepancy of maturity ratings come from. From my perspective, I find Resident Evil more graphic than Assassins' Creed when it comes to violence. Are Japanese rating agency being more strict towards Western games or is it simply a difference in culture when it comes to what is acceptable?
