When going through the list of developed countries I realized that I never heard about the Japanese (PC) gaming scene before. Why is that? Surely the games that we play get shipped there as well, that can't be the reason. Maybe it's the language barrier and those guys don't post a lot on European/US sites or only have their Japanese communities.

Most likely they are more into console gaming but I don't know if there's a professional scene for console games. They have some talented overclockers for sure and the tech loving kind of people Japanese are, they actually ought to have a lot of talented people who spent endless hours with PC games and should be internationally known, not?

Well, perhaps I just haven't noticed them, hmm..
