Of course, if someone were really into this sort of thing they could make a DNF-2001 style mod - you could even use eduke and make it look much better than the game would have been in 2001.
Things that made the 2001 trailer fun and exciting that isn't in DNF. Practically everything (motorcycle, interactive food machine, everything doesn't look like plastic, too contrasty, a mine cart ride at a las vegas attraction, and much much more). Seriously, the fan trailer was as good as it gets. :/
