Hate to ruffle feathers continuously (and remember that the fact I can say so much about it does mean that I played the game), but the more I think about it, the more Dracula X just irritates me, and not in a fun way.
In Rondo, there were chicks you could save if you figured out a simple puzzle that was isolated to that level. It was kinda cool, gave your system a chance to show off its fancy redbook audio that was enough to support bad voice acting, hey, neat. But you could figure out the puzzle, save the chicks, and be done with it. It was simple.
In Dracula X, they condensed this feature down to one insanely ballbustingly hard puzzle that spans over three levels of the game. And there isn't even the reward of getting to see a badly acted voiced cutscene from it, just a few dopey lines of text and a different screen at the end. Oh, and you get to fight Death, too, which, while not wholly unappreciated, seems like something that should just be "in the game" and not need to be unlocked.
Playing Dracula X feels like a chore. When I play Rondo, I feel like I can relax and have a good time.
