I only own the pc98 versions of this game. Of course the graphics aren't as good as the pc-engine version, but it has...ummm... more adult stuff in it. I would like to try this one though. I wonder what the game sounds like? I have seen this game go for less than Dracula-X.
The PCE version also has some "adult content" (the cover announces a +18 restriction), but it's rather soft (really, really soft. Shall I say that Kol c.... .. ... ...........?).
