Oh.. May I know how you arrived at at conclusion
I came to that conclusion using the undeniable veracity of stereotypes.
By your logic, most of the guy's here who play shooting games are American and you mean to say that the Japanese don't play a single FPS/TPS game out there.
Japanese peoples also have ridiculously small houses that can't even accommodate an Xbox . They also only play games featuring huge bug eyed and underage protagonists.
I this is the effect of the latest version of Ace Combat. The game is also very highup in the software sales.
That seems much more plausible.
EDIT: And yes it is.
