Metal Gear Solid, when Psycho Mantis was saying, "You like Castlevania, don't you?"
Resident Evil, when Chris Redfield said to Jill that she was almost a "Jill Sandwich".
Castlevania: Symphony of the Night when there was going to be a duel between Dracula and Richter Belmont in the Prologue.

That's why you gotta love the PlayStation.
