Awesome Music: The best part of Dracula X Chronicles is that you can set any song in the game, either original or unlockable, to play in any stage or fight you want, with the exception of the fight with Dracula (except in the PAL version). Who doesn't like the idea of using "Bloody Tears" as the boss theme, or using the previously unused remix of "Cross Your Heart" as a stage-theme?
The low-quality 3D visuals in the Rondo remake, which wouldn't be so bad if it wasn't for the original game requiring unlocking and having sound issues.
While remixing the soundtrack for the remake, they took out "Den", the Clock Tower theme unique to Rondo, and inserted "Moon Fight" from Castlevania Chronicles in its place. The original version of "Den" is still available, but this decision remains a odd one.
