I think Castlevania should be about Dracula and his rivals, the Belmont clan. I think IGA's storyline got too convoluted with side stories and unimportant characters. I don't think the conflict between Dracula and the Belmonts was personal enough, and emphasized enough.
I think the problem with LOS is that it took that a step too far in making Dracula a Belmont. They have made Dracula an interesting hero, but they have also made him less of a villain, and far from the monster the character is supposed to be.
I see Dracula as man corrupted by a lifetime of war and imprisonment. A man with nothing but vengeance and self entitlement in his heart. He inflicted unimaginable pain and suffering on his enemies and even his own people. Dracula committed the worst massacres the world had ever seen. He demanded perfect obedience and slaughtered anyone who disobeyed even the most trivial rule. He had not one shred of mercy in him. This was the man he was during his natural life. Imagine a man like that given the powers of a vampire. He is a horrifying monster. This is the character Dracula is in our game.
The Belmont clan was also never given what I feel is the right relationship with Dracula. Dracula was in fact killed by an assassin. This is what is widely believed. It is most likely that this assassin was either a Turk, or a Boyar (the class of people Dracula showed the least amount of mercy to). I have let history be my guide in shaping who the Belmonts are and what their motivation is behind their campaign against Dracula in our reboot.
The name Dracula was more than a moniker, it was Vlad Tepes' patronymic name. He is the real Dracula, and even in Bram Stoker's book, he makes countless references to holding back the Turks. It obvious in Stoker's book who Dracula is.
It feels awkward to me when the character of Dracula is twisted into something else. Especially when he is such a fascinating character to begin with. He is perfect as he is for Castlevania, there was never a need to twist him into someone else. He is tragic and terrifying. A perfect antagonist.
I wish Konami would use what is right in front of them to get the story right.
