A project (usually a video game) that has taken so long to complete that one of two possibilities exist: either the project
will never be completed, or in the even that the project is completed, it
will be so crappy that it would've been better off never being completed. The term is derived from Duke Nukem
Forever, the most famous example of this.
I want Beyond
Good and Evil 2 released just as much as the next red-blooded
gamer, but at this point, I'm pretty
sure it's a DNF.
