I don't mind it either, I mean no one says anything when Dracula has had a replica of Atlantis under his castle. But a lava filled cave with a mine cart is wayyyyy out of place.
Eh, Dracula's castle is always full of unsuspecting, oddly out of place things that I don't even think he knows about, so it shouldn't be a surprise to anyone. Now what would be out of place is a underground nightclub with a DDR style minigame with ghost dancers.
Is it scary that I could actually imagine that? Oddly enough, I had a dream that if Dracula's Castle appears in modern times, soem of it's interior contemporaizes itself to match the era. Not completely modern, but with some modern traces. It was a strange dream, too. I was in some art gallery with other people, and pushing this lever, a giant statue rose and revealed a pathway under it, leading to a hallway(with floor panel lights) and a doorway that lead to some sort of mausoleam that looked straight out of the Phantasm movies. That's justa theory.
Considering the whole mine thing, though, anybody wonder if they plan on touching up on the nature of the castle in this game? I heard they are still calling it a "creature of chaos", and it still changes depending on it's master. We know it's nature in the original canon, but I wonder it's power's extent in this one. And if there was any game in the LoS to address this, MoF would be it(you experience the castle in different parts of time, and witness the changes of the castle in each era).
