Not at all - we still print articles for the D&D rules system, as well as any other gaming system. It all depends on reader submissions. (In fact, there's a new D&D v3.5 monster variant coming up in issue #138.)
(The free KODT 132 PDF has submission guidelines at the end, or you can get them separately here.)
"I waste em with my crossbow" is a standard part of my gamer lexicon, so you can consider me a fan.
Granted, I'm one of the fans who prefer the comic section as opposed to the rest of the magazine. I do enjoy the 'Lost Games' section now and then though.
