I'm about to say something that is sure to get me a few negative votes on this post.
As much as I love SOTN, I would have much rather had a sequel to SCV4 than SOTN.
Let me clarify. I think a sequel developed by the same team that made SCV4, in the open world style of Simon's Quest, would have blown SOTN away. Just imagine a game with the mechanics, music, and graphical style of SCV4 in glorious 32 bit, with an open world adventure and character development. Just the thought of that sends a tickle down my spine.
I also think that it would have pointed Castlevania in a better direction for the long run that SOTN did.
I got a boner while reading this post. xD I'd LOVE to see that!
Another thing I think is interesting about SoTN is the glitching thing. Its utterly ridiculous but I remember for a period of time it was interesting to see when they'd get a few more rooms over at World Beyond Walls.
