All of the Castlevania games before Harmony of Dissonance were called Dracula , or Akumajou Dracula originally Cap'n. Besides, even if it was called "Sauna of the Undead Sucker Killer Machine" anyone slightly familiar with the series could tell it was Castlevania.
PS: Harmony of Dissonance and Aria of Sorrow are both much better. Unless you want extra play modes.
I am a Castlevania nerd.
