Looking Back...
Our initial target release date was November 1997, a year before the game actually shipped. This date would have given Valve a year to develop what was in essence a fancy Quake TC (Total Conversion, all new artwork, all new levels). By late September 1997, nearing the end of our original schedule, a whole lot of work had been done, but there was one major problem, the game wasn't any fun.

Also, John Romero has a .plan update commemorating another anniversary of Doom's release.

The looking back thing by Ken Birdwell is pretty cool. It might give a little insight to people that have never been involved in developing games as to how things work. Also as to why things slow down and are released late.
I\'d like to note that I was told Romero at one point scrapped a shitload of levels much the same way Valve scrapped their game. People do these things because they want to reach for a higher quality game instead of releasing shit (blood 2 for example:).
