Looks like we might be in business...
Thats not too bad seeing as western reviewers especially big name ones like Gamespot and IGN. Tend to be biased against Japanese games with an anime aesthetic(the more cute the more bias).
USUALLY, said reviewers, especially IGN and gamespot, only give Japanese games high marks if it meets the follow catagories.
Is a game from a Super Famous IP and/or super famous game developer/company. Examples include: Mario, Zelda, Donkey Kong, animal crossing, final fantasy, Sonic, street fighter etc.
Is a game that is basically a Western Game made in Japan or atleast a game that is a love letter to western games or western culture. Examples include: monster hunter, Demon Souls, Metal Gear, Vanquish etc.
A game that is dark and edgy and or super violent. Examples include Persona, SMT, No More Heroes, Bayonetta, Catherine. Etc.
There are some exceptions but this generally is the case.
