I think I am with Piratecat one this one. My gut instinct is to say now. Unequivable, Now , Now, Now

is the golden age of Dungeon, Dungeon is better than it has ever been.
I am impressed with what they are doing with Dragon. I too have very fond memories of the Roger Moore era. The magazine was alot broader in those days, being able to cover D&D, Top Secret, Gamma World, etc and had a regular space opera feature. The game was still fresh, so articles that had rules on how you could fight with two weapons, or had NPC classes like the Anti-Paladin, or the Beast Master, or the Dreamer, or the first ecology article, like that of the oytugh were revolutionary.
Today the current magazine faces so many new challenges. Much of the D&D community have grown to despise Prestige Classes, so the 3.5 equivalent of NPC classes is no longer a strong option.
Ecology Articles for mundane creatures have grown old hat, and the magazine today, unlike that of what people term the "golden age", is published in a climate of aggresive rules promogation by WOTC.
The fact the magazine is so good today, speaks volumes for the effort that goes into it.
