You can quote the same thing from that Wiki page as many times as you want. Since your point was that vampires don't exist in the game, all you need to do is a quick look at dictionary.com and see you don't even know the definition of "vampire".
vam·pire? ?/?v?mpa??r/ Show Spelled[vam-pahyuhr] Show IPA
–noun
1. a preternatural being, commonly believed to be a reanimated corpse, that is said to svck the blood of sleeping persons at night.
2. (in Eastern European folklore) a corpse, animated by an undeparted soul or demon, that periodically leaves the grave and disturbs the living, until it is exhumed and impaled or burned.
3. a person who preys ruthlessly upon others; extortionist.
4. a woman who unscrupulously exploits, ruins, or degrades the men she seduces.
5. an actress noted for her roles as an unscrupulous seductress: the vampires of the silent movies.
You're really digging deep now. If that was the definition you were referring to then yes, there are vampires.
However you clearly didn't mean that definition. You were talking about mythological creatures, classic Hollywood horror.
You clearly meant the classical vampire...the primary definition, not the third definition down. You do yourself a disservice pretending otherwise.
Edit: What was the deal with Georgetown? Don't really remember it that well.
