JoannaK: Please enlighten me about Boxxer.
I ment no offence, I believe that the better AOS4 is when it is released, the larger the chance of success.
But there is a balance to speak of as well, if it is released in 4 years from now it will be worthless because of the technological advances made.
Anyway, DNF is doomed, and has been for quite some time.
They began testing with the Quake-engine. After the release of quake 2 a DNF beta appeared (based on the q2 engine). There were even a few screenshots from that beta. But the beta was discarded as it was out of date long before it was ready. I think they tried the q3 engine, but that is out of date today as well.
