I think the game isn't calles Akumajou Dracula in Japan, just look at the website even in Japanase, the tittle says Castlevania. In the japanese magazine's (I don't remember thename) webpage where there was a interview with Kojima, it was called Castlevania, not AD. Let's accepit, they want to occidentalize it.
That's not a problem, I think IGA was very closed to new ideas, the japanese people is very mystical about their things, yes, that's their tradition, but some of the people (The most) don't like that, if the saga needs a good reboot, I think we are in the right way. And if you don't like the game, but it result to be good, IGA would be a dumb if he doesn't learn about this and make the typical pseudo-goth-japo-castlevania with a good gameplay.
