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.

um. Western rpgs GET?^_^

Personally, i dont like japanese RPG's, its too linear, and the character development(gameplay-wise, not storywise) is close to null compared to the western systems.
