I said this once, and many times before I shall say it again. It's not Nintendo that's the problem. The problem is Japan. Ever play Final Fantasy 11 online? How about PSO where you can't use the word, "shoes" in a chat room? Don't forget the outright lack of voice chat for Resident Evil Online 1&2! MGS3 Online was a great step forward, but that game had no chat room! Look at any Japanese online game on the market, and notice the lack of the basics.
As I said before the problem isn't Nintendo. The problem is Japan itself. They need to change their mentality before making any more online games.
