Wow, that was... different! Props for doing something so odd this time around, even for ZP's standards!
Since I never had a decent computer in the mid 90's, I never knew much about Duke Nukem to begin with, but that's a really great point made about our industry that a developer could spend twelve years on a game and never show anything for it, while brilliant independent gamers are being snubbed. Executive meddling ruins everything!
Still, it's a shame that DNF probably will never come out. After all of its development time, we should have expected something absolutely astonishing... anything below that would be considered a betrayal of trust. Now that the project is halted, it's more of a kick in the balls than a simple betrayal of trust.
