Same here. The US version was hard, but not near-impossible like, say, Ghosts 'N Goblins (which I still can't even beat once). But I still prefer the Famicom version. The music is better, and it's a much easier game to get through if you just want to go back and experience the game again.
I heard somewhere that the Virtual Console version of CVIII was actually a tad bit harder than the original US release (because of the longer laser beams from Dracula's final form, if I remember correctly). But I'm not sure how valid that is.
Oh my god, Ghosts n Goblins isn't even hard, its just plain cheap and unfair

I don't blame anyone who can't beat it. True, CVIII isn't near as hard as that game, but I guess it boils down to the fact that I haven't played CVIII nearly as much as a kid and through my teens. Same with Bloodlines, I'm just not as used to it as I am CVI, II, IV, and Dracula X, or even the FC version of III. I'm sure the same goes for everyone with certain games too. I can't get past the aqueduct in III, but beat it with just Trevor(or Ralph lol) in the FC release.
And if that harder Dracula on the VC release is true... Common

as if I wasn't good enough already.
