Hi, Nintendo.
I have a marvelous idea.
Lets really commit to releasing all the high quality games that you developed in-house at your own expense in the U.S. (at least). I feel you should do this because that market is oh, triple the size of the Japanese market and has quite a few peoples who like video games.
No, seriously, commit and be vocal about it! This is key too: no coyness is required, your customer base will appreciate the transparency and commitment to provide content! And after all, they know the distribution cost in the case of projects like Harmo Knight are greatly reduced thanks to digital...they just want convenienty obtainable and reasonably-priced content.
If you are worried about whether or not a game can "sell in x market", well it is time to start hiring and firing marketing and sales peoples until you find the ones that can sell a good game to a very large, paying market.
Please do your best, lots of customers are counting on you! -xoxo Unky_Op
