Been reading a lot of episode summaries on Memory Alpha lately. In a lot of cases the final product is a lot different from the original concept. Especially what we now see as the sub-par episodes. Some of the better ones:
Rivals - Trombetta himself said it was extremely frustrating developing the story, "because there was this subplot of the racquetball game that they had wanted to put in a number of times and had not been able to, so they put it in this [episode] after I was gone because they felt it made the most sense since this was about games." He goes onto say, "I would have liked to have done more with the quantum-luck thing. I had the idea that if randomness could be managed, then you're in a lot of trouble. Basically, the universe is random; it's a mind boggling thing.
Armageddon Game - Writer Morgan Gendel's original pitch for this episode involved a Federation team going to an alien civilization and demanding that they destroy their biogenic weaponry. However, the alien race encode the weapon into O'Brien's DNA, meaning that if the Federation want to destroy the weapon, they must kill O'Brien.
Honor Among Thieves - Philip Kim's original idea for this episode was a comic story involving Jake saving the life of the daughter of the Orion Syndicate's leader, and, due to his actions, Jake is befriended by a number of high-ranking Syndicate members. At first, he loves it, with his new friends able to get him anything he wants whenever he wants. However, Jake and Nog have a small argument on the promenade and the next day, Jake discovers that Nog is in the infirmary after suffering a nasty beating. At this point, Jake realizes he's into something he can't control, and he goes to his father for help. The comic element of the story was to come from the fact that while Jake is trying to extricate himself from the Syndicate, Quark is trying to work his way into it, so he decides to become Jake's new best friend.
Destiny - The original story idea revolved around Starfleet seeking to relieve Sisko of his post. As David Cohen recalls, "We had enjoyed Deep Space Nine's pilot and the mythic overtones it suggested, as [Commander Sisko] was believed by an alien race to be the 'Emissary' from their gods, as prophesised in their scriptures. It occurred to us that Sisko's bosses couldn't be very comfortable with that. What if they pulled a Heart of Darkness on him and sent someone to extract him from this situation? The perfect chance to do so, we decided, was if there was some specific prophecy, that would, ipso facto, prove he's not the Emissary. We'd raise the stakes by having a pencil-pushing staff officer threaten to transfer him to another command if he doesn't end this 'Emissary' talk."
Playing God - In writer Jim Trombetta's first draft of the teleplay, the A story was the protouniverse story, with Dax's storyline in secondary position. Michael Piller rewrote the episode to place the Trill storyline as the primary plot. Trombetta felt that this decision robbed the episode of its emotional balance and that the ethical problem of the protouniverse story is no longer felt on an emotional level.
Second Skin - Robert Hewitt Wolfe's original idea for this episode revolved around O'Brien discovering that he was a deep-cover Cardassian operative who had replaced the 'real' O'Brien twenty years previously and had had O'Brien's real memories implanted into his own mind. This would have meant that the O'Brien we first met in "Encounter at Farpoint" was actually a Cardassian spy.
The Wire - Robert Hewitt Wolfe's original idea for this episode was to have Kira addicted to battle stimulants ever since her days in the Bajoran Resistance, but that idea was rejected because it would be difficult to do subsequent episodes with Kira without referencing the addiction and it was felt it could tarnish her character too much
