Yes, I was having difficulty learning how to play DW, too. Irritating since I have a degree in physics. I mean, I took differential calculus, multi-dimensional calculus and modern physics classes...all of which were easier than learning DW. Argh!
But then the sub command pack thingy came out and I plunged into Sub Command and 688. Both were a HUGE help when it came to playing DW, especially since a lot of the interface is the same, or similar.
DW is fun, but the learning curve is way too steep for anyone who hasn't had prior experience with something easier to learn (notice I didn't say easy) like SC. My two yen, anyway.
