Back in the mid 80s, Konami released a game called Castlevania and the rest was history. Over the next 20 years, The series became known for it's daunting challenge, level design, and tight control, but unfortunately, they have also, in my opinion, led to the rise of these cornball ass Vampire love stories that teenyboppers are sprung on lately. Let's be real for like two seconds; nobody gave a shit about Vampires like that after the old Bella Lugosi movies. Blacula couldn't even help make Vampires more than a cornball stereotype for Scooby Doo to catch. So, in my humble opinion, Castlevania can be credited to the world starting to pay attention to teen angst drivel like Buffy: The Vampire Slayer, that Twilight bullshit, or even True Blood should send thank you letters and emails to Konami and the estate of Bram Stoker, of whom the backstory is loosely based.
...That was my opinion. If you don't like it, build a bridge and get over it.
