Well, Waffle, Drac could just go for the modern equivalent and take over Trump Tower.
As for the Succubus thing (ohp, Plot just posted, so he's probably going to say the same thing only better), I think that has more to do with Alucard's deep - almost symbolic - love for his mother, and the fact that he comes off as asexual, more than an implied Oedipus complex. I mean, the guy's got next to no emotion for anything
except Lisa. A large amount of his dialogue is pretty aloof in tone until Lisa comes up in just about any context.
I guess, in a sense, the Succubus (God, I wish she had a fucking name) isn't so much tempting his dick, as she is tempting the other half of his dhampir nature.
Hang on a minute...a dhampir, who's more human than vampire, who sympathizes with and works to help humankind, who is the son of Dracula, makes every effort to control his bloodlust, and has a deep-seated and profound love/hate relationship with his origins...
Where have I heard this story before...?

Oh, right.
EDIT: Yep, Plot did. lol
