CC isn't vaporware because it's finished right now. I can and am playing it. It may not have all the stuff Data wants to eventually be in it, but be honest. If someone said they where making "soldat with amazing destruction physics and easy modability", that's more than a viable game. Maybe it's not perfect, with lackluster AI and no online play, but it's still a fully-fleshed game in it's own right, and has been for a while. I can definitely see Data wanting to have at least one of the two of those before he considers it properly done, but it's not like you can say "hey I payed money a while ago, and there's still nothing remotely playable". For that matter, I don't think you can call anything with an open beta vaporware, because if I can buy it and I can play it... what more do you want as proof it can sell?

DNF is/was/may still be vaporware, because all you get are promises that it will work at some point. I'd personally say there's been several games of the same title that have all so far turned out to be vaporware, because do you really think it's actually been continuously developed for all this time? This new one could just as easily have been called "Duke Nuckem: some title".

In my opinion CC is far far done already, we are just not yet used to this kind of new game type.
