Yep that Castlavania, and for some reason I really like it, it was my first time ever playing a Castlevania. I know that many people say this game really sucks and shouldn't be part of the Castlevania storyline, well I never heard of Castlevania until I played this, I do like the story and the characters; I usually play as Carrie. Now when I first played this way back when it scared the crap out of me, yes you read that correctly, just something about it made me a tiny bit scared and I would only play it in the morning, I scare easily.
So can only imagine what people might say but I really like this game, I don't know why, I just do. The only other Castlevania game I played was Curse Of Darkness, I am thinking about getting some more of them when I have money and more time on my hands.
Anyway, I'm a huge Castlevania fan, as some over here knows, but I..kinda enjoyed Castlevania for the 64, it was a guilty pleasure and of course it had many problems, like controls, camera, design, etc etc, bu it was still a good N64 game.
Also, it isn't part of the storyline. Also Also, who cares? Castelvania isn't about storylines.

I have to agree though, get some 2D ones.
I miss the old castlevanias, the new metroidvania style is really fun but I like to go back and play Castlevania 3 for the NES, that game was so good.
I too enjoyed its nightmarish design, its something that grows with you. Take your time, and enjoy it as well.
