I wonder if there really are any NEW Castlevania fans. I mean, the only people who play the new games are people who were already fans of the series from the old NES days. The newer games aren't GREAT, and they certainly aren't groundbreaking like the old ones. The newer games alone probably couldn't make someone like the series enough to go to fan sites.
Then again, I'm completely biased. C3: Dracula's Curse on NES was the best Castlevania game ever made.
