Game developer and director of Kojima Productions, Hideo Kojima, provide insight into the Japanese side of game development: "A lot of creators are just focused on Japan and the Japanese market and aren't really aware of what people around the world want."
There's no denying that western developers has seen much a bigger growth this generation. A lot of Japanese games have at most a niche following outside of Japan, but I don't want to see them completely westernised just to garner a bigger audience. I play eastern games precisely because it's a nice contrast to the Call of Dutys and Need For Speeds of the west.
If anything I think more people should open their minds to the delights of Japanese games.
