Dracula X is a pretty weak version of Rondo. Rondo just has better Levels and music IMO. And the difficulty is a bit more balanced.
I WOULD give props to Dracula X for a pretty interesting Dracula fight, what with the bottomless pits, if it werent a real dick move due to how you get knocked right the fuck off a platform when taking a hit in the wrong spot.
What would you even call it anyway? it's not a port... Well, it's like, half port, half original game... we COULD call it a de-make, since it has inferior qualities to it due to not being a CD based game like Rondo.
No seriously though, what do you call a game like Dracula X?
