Comparing this to DNF is just wrong.
Rimrook's done a tremendous job with all graphical aspects of the mod, where not only the demo's finished, but also most assets for the actual game are nearly made.
As for the code department - hell, it's playable right now. Only things holding it back code-wise are some bugs with the new gameplay mechanics, some unimplemented side-features and general polishing up.
Not saying it's finished, though it's pretty damn close to that.
