I have to disagree with Tats. It is worth playing XX, and I think you can have fun with it. It has flaws, yes, but I think many folks would enjoy noticing the differences in the games.
An old member here once described XX as a "remix" of Rondo. I think he had it right when he described things that way, except I'd modify things by saying it was a "budget remix" that lacked the polish, creativity, level design and the Fun Factor* (i.e. Maria!) of Rondo.
To continue the discussion on Dracula XX's merits:
I actually like the burning buildings / wavy land, with all the embers raining down because it achieves its goal rather well: to create the feeling that you are in an inferno, that all hell is breaking loose, and that tension is building...
This is an example of "wavy sfx" contributing to the atmosphere of a stage and not simply being a gimmick, novelty, etc.
And the music in XX is good.
I like XX.
But:
XX can't compare to Rondo. The polish on Rondo was always evident (and awack is providing evidence to bolster the case).
That said, I'm glad we have both games to play.
So...
More comparisons, awack!
