This time it's Chadmium, whose module Legacy of the Dracyn has hit 8000 downloads and made it to the Hall of Fame. They talk about a couple of personal things, as well as Chadmium's priorities in module making. Here's a snip:

4) Could you tell us what are the main features of your modules that have attracted so much attention from fans?

I put a huge amount of effort into the visual effects of my modules - I think visuals have a special way of enhancing immersion, and some of the combinations possible with the Aurora toolset are truly breathtaking to behold.
I also like to think that fans enjoy the density of my modules. They are both short in length and small in size, but packed as tight as I could make them. There are no huge, sprawling areas to wander - at no point does the player have to wonder what to do next, they adhere closely to the plot, and I tried to make conversations and battles few in number, but high in quality.

To give you an idea, I spend at least 60 hours of building time for each single hour of play (more when I was first learning to script).
