As cheesy as it is, I'm so used to the name, that I would personally prefer Castlevania as the main name. It's kinda like how cheesy Superman, Wonder Woman, Power Man, Ant Man, etc. are, but I'm so used to those names, that they don't sound cheesy. If they were to be created now, yeah, Superman is gonna sound extra cheese, but growing up with it(not that I'm a fan, he's too much of a boy scout) I'm totally used to the name.
