Why Are Japanese-Developed Games Less Popular?
Thanks to GameSpy for their 'Sole Food' editorial discussing the decline of the Japanese-developed videogame in the U.S. console charts. The article doesn't deny there are still big Japanese-developed hits in the West, but suggests: "It's not uncommon for there to be only two or three Japanese games among the top 20 sellers each month; this would have been unheard of less than ten years ago." As for explanations, it's argued that "Western developers are doing a better job of servicing core genres that are popular in the U.S.", but a "financial and creative slump" in the Japanese games industry is also blamed - "A quick glance through the games shown at last weekend's Tokyo Game Show reveals little that is truly new."
Perhaps it's for the same reason that US developed consoles aren't popular in Japan:
It's cultural
If you could be anything you want, I'll bet you'd be disappointed.
