AoS feels like the natural ending to the timeline though. You defeat the chaos within the castle, make the castle vaporize, reject your fate of becoming Dracula, thus ending the eternal struggle between Belmonts and Dracula, and giving Mathias a second chance at Humanity with someone he loves.
Alucard thanks you in the name of his mother, and Julius feels the power slipping from Vampire killer. (Probably Sara's soul finally being able to rest and therefore leaving Vampire killer) It all feels so final and so absolute. And it worked, it was well done.
The came DoS and fudged all that up.
