HomeLAN Fed has posted an exclusive interview with BioWare CEOs and senior staff members on paid download of premium modules. Here's a snip:

HomeLAN - First, has the Aurora development tools for Neverwinter Nights been a success in BioWare's opinion for fostering new mods and modules for the game?

Jay Watamaniuk - It has most certainly been a success in our opinion. I would go one step further and rest the success of the Neverwinter Nights vast community on the shoulders of two things; the inspiring talent of that very community and the Aurora Toolset itself. They are linked together. You can hand over the best tools in the universe but if they are not used then your effort has been for naught. In our case we had the good fortune to spark the imagination of not only the veteran modder but a group of people who only previously played RPGs and never thought to create their own worlds. There is an excellent balance of usability for those beginners with enough advanced flexibility to keep the veterans coming back in the Toolset.

True, since it's the custom content that is keeping NWN thriving, and this time, you indeed don't need to be an expert modder to create some, though it still helps :)
