WHY DQ isn't popular in America

Hello!Nice to meet you.
I'm a Japanese.
Well...I have a question.
Why the Dragonquest (In America it called DragonWarrior) isn't popular in America?
DragonQuest is most popular RPG in Japan (than finalfantasy).
It's wonder for me.
WHY?
Could you tell me your thinking(opinion?)about it?

Sorry,Poor English.

I thought he was asking for factual data stuff though, that's why I didn't post that. :<
I've only finished the first DQ game....and that was only as a hack where you played as Mario. Couldn't pull more than an hour or two out of the ones after. Even old PC RPGs are less boring to play. I'm guessing it has something to do with national attention spans, see: overabundance of textual dating sims over there. They got patience to spare, them Japs. Maybe DQ8 will change the way the series plays enough that it's not totally boring to the rest of the planet.
