I don't see how the adventures of a boy who grows into a man, has a wife, kids, a castle and more is generic. If anything, the stories in Dragon Quest IV, V, and VII are more novel, better written and ballsy than anything in the Final Fantasy series bar VI.
What about the part where you're turned to stone in Dragon Quest V? Along with your wife, you're turned to stone in a faraway tower. You just became a father, you've only seen your children once. Then you're carted away from a merchant who thinks you're a statue. You stand around, treated as a lawn ornament as you watch the owner's son grows up as your own children live life fatherless. There are hardly any words in this one scene and the emotions evoked equate to weakness, you're truly feel weak during this scene.
That one scene is probably more powerful and better written than any Final Fantasy scene. So much for "generic".
It's just that it seems that (and this seems to have been proven with this entry) there's a subset of FF fans who are completely incapable of appreciating adventure. FF games and DQ games are complete opposites: FF games are about the characters, DQ games are about the world, which is the character.
I'm convinced that if you think Dragon Quest games are generic you have the imagination level of a doorknob.
