Is it more satisfying as a writer to be able to work on something that had the structure of Deep Space Nine?
I enjoyed it much more because it meant the characters and the station could evolve. The mission could evolve. You could change things gradually, and see how relationships played themselves out. On the truly episodic level of Next Generation you just got a sense of "I wish I could follow this story more."
With DS9 and Sisko you could keep returning to things that were established in the pilot like his relationship with the prophets, and his position as the emissary to the Bajorans. How he grew into that role was something you could take your time to develop. The only thing you could really do like that on Next Generation was the relationship between Riker and Troy. Even that was in very small doses.
When we did Sins of the Father with Worf, that was the first time Trek had ever really done a continuing story line and it was a departure for them. I really liked it because I wanted to keep coming back to the tale of Worf getting his honour back and what that meant.
