what he meant. People are just latching onto the original choice of words. Personally I understood what he meant all along.
Leonard Nimoy has discussed the time he was evaluating whether to agree to appear in Star Trek: Generations
. Reading the script, he frequently found himself going, "Why is this scene here? What is its function?"
He was thinking of how the story worked as a whole and whether the scenes had sufficient dramatic motivation. Obviously the question is somewhat different with an adventure game, but it is true that nothing in the original game even hinted at either these mer-creatures or any of the political intrigue we see in the remake.
Obviously the idea was to add depth to the story. But whenever new elements or chunks of story are added, it affects the balance of the whole. In this case I felt the mer-creature plot detracted from the mystery and majesty of Neptune's domain, and the political intrigue plots ended up rewriting many of the characters into something completely different.
