I'm a huge cynic when it comes to Nintendo of America. I think just about all of them are a bunch of douches who don't even like video games. No matter how awesome a Nintendo of Japan game may look to me, I can always count on Nintendo of America to just not get it and leave that game unlocalised.
I feel like NoA is run by the types who made the American Mega Man cover art. They somehow ended up in charge of bringing a product to America that they don't even like. This is why already localized games like the Tingle RPG and games with huge rabid American following like Earthbound 2/Mother 3
don't come to the states.
In case you forgot.
