I sometimes honestly wonder, why I haven't actually went and finished learning how to speak and write japanese and gotten my ass out of the county yet.
You should probably focus more on your English.
On a more serious note, not all JRPGs are good. Hyperdimension Neptunia was quite frankly a crappy game, and I'm pretty sure there are others that are crap. Equally, there are games made in Japan that just don't apply to North American desires for games. Visual novel games are very popular, but this genre does not cling very well with North Americans. It's all about the money: it takes money to bring these games to North America. Companies want to make profit. I think you can do the logic here: if a game does not cling, it will most likely not sell enough to make a decent amount of profit.
That being said, I also have to disagree with the whole "America has gotten pretty stupid when it comes to games" comment, seeing as I, and several others, enjoy North American titles. Call of Duty isn't the only American title out there. Actually, I'd have to say "America" is pretty damn smart when it comes to Call of Duty; the sales that rack up from those games are pretty high, thus making a lot of income. This is pretty smart for a company.
Oh, when I say America, I mean North America. GM seems to think it's a country. Last time I heard, it was the USA
(being a smartass Canadian here).
