Of course by this argument, story is NOT more important than canon. "We can't introduce a new race because that race was never in any of the TOS episodes" is just as bound by minutia as "Hey, how come we know so much about the Gorn now?" More so, really. Somehow I suspect SNW will continue to introduce cultures we never heard of in TOS.
I sure hope so. And yes, I agree to your point which is why I discard minutia at this moment. I did the Trek encyclopedia thing and you know what I found with it? Boredom. It became an excise in utter frustration and then people would use that knowledge to box me out of conversations. That's frustrating. It's when I decided that continuity/canon are not that important to character and story first. Could they do a race not the Gorn? Yes, and would be just as shellacked for it as now.
So, might as well expand on what we barely knew we knew.
If you want to argue that one can no longer enjoy Star Trek without first refreshing you knowledge of every detail that was written about Klingons over every show and movie over 50+ years, that's minutia. You can learn everything there is to know about the Gorn in less than an hour. That's not minutia, that's an episode.
And what do we know? And what is contradicted?
Somehow we have managed for nearly 60 years with one appearance. Where they are depicted as capable but territorial space travelers that can eventually be negotiated with.
Really? Negotiated with? After wholesale destruction and Kirk having to beat him with a rudimentary firearm?
From a transcript:
KIRK: No. No, I won't kill you. Maybe you thought you were protecting yourself when you attacked the outpost.
(He throws the dagger away, stands up and shouts to the sky)
KIRK: No, I won't kill him! Do you hear? You'll have to get your entertainment someplace else!
(The Gorn disappears, and a young blond boy in a white shift appears instead.)
KIRK: You're a Metron?
METRON: Does my appearance surprise you, Captain?
KIRK: You seem more like a boy.
METRON: I am approximately fifteen hundred of your Earth years old. You surprise me, Captain.
KIRK: How?
METRON: By sparing your helpless enemy who surely would have destroyed you, you demonstrated the advanced trait of mercy, something we hardly expected. We feel there may be hope for your kind. Therefore, you will not be destroyed. It would not be civilised.
KIRK: What happened to the Gorn?
METRON: I sent him back to his ship. If you like, I shall destroy him for you.
KIRK: No. That won't be necessary. We can talk. Maybe reach an agreement.
METRON: Very good, Captain. There is hope for you. Perhaps in several thousand years, your people and mine shall meet to reach an agreement. You are still half savage, but there is hope. We will contact you when we are ready.
Not sure where the Gorn are shown to be able to be negotiated with.
