Here's a question that's not related to DQ.
Dark Tower and Caverns of Thracia are two of my all-time favorite adventures. One of the most appealing aspects of these adventures are their awesome maps. They have a level of complexity that is only very rarely found in published adventures (actually the only other one that comes to mind right now is the original Ravenloft from Tracy Hickman). Having a challenging, non-linear dungeon layout is very often already a guarantee for success of the adventure as a whole. I've observed more than once when DM'ing your modules that the players find great joy in figuring out the lay of the dungeon and discovering all those different linkages between the different levels.
I once tried to design a dungeon with a similar complex layout like Caverns of Thracia and found it not to be easy at all - in fact I found the result to be a failure and never finished the dungeon.
Now here's the question (actually three questions): When you design your adventures (and draw the maps for them), do you draw three-dimensional maps before to visualize the complex layout better? How easy is it for you at all to design a sophisticated map? How long did it take you to create a complex dungeon map like the one for Dark Tower for example?
Thanks for answering - great to have you here!
