My first post on the subject. How exciting.
I've heard some pretty hilarious stories about Haunted Castle, but I've never had the (mis?)fortune to play that one myself. Of the ones I have played, though, Rondo of Blood certainly takes the cake for me. I'm not sure if it's because my hands are reacting instinctively to a console controller that is not there or what, but I don't recall any of the past games being anywhere near this difficult. And while I'm aware that a lot of people find Bloodlines challenging, that was my mainstay game as a lad, so I'm used to it. It'd be nice if Rondo had a difficulty selection feature like that game did.
