First of all, I hugely appreciate your taking the time to read through the whole darn thing and give such detailed feedback. Round of applause for Green!
And now, to business.
Things to improve:
-Thanks for all the grammatical feedback. I'll try and get that all sorted out tomorrow. Not sure how my spellcheck software missed the "ivaccumternational" one, lol.
If you need help finding the third ending (Warrior Nation), you need to fail your negotiations with the Selei, succeed with the Kaagar, and then choose to help the Kaagar attack and defeat the Iridians. After that, it's a cave-of-time style path that leads to the third ending. If you need any more help finding it, let me know.
Narrative feedback:
1) That was deliberate, which I talked about a bit in my response to Helpful Conisseur. I felt as though not giving the player the opportunity to state their opinion would be off-putting, but that there was no way the other diplomats would vote in any other way. It was also meant to escalate the sense of danger from the effect of the headsets. If it just comes across as irritating instead, let me know.
2) The "Federation" ending is probably the closest you come to that, since you're allied with the Kaagar, Iridians, and Dek, and are on good terms with the Selei. A true "Utopia" ending would exceed the scope of the story, since forming binding relationships with the Selei and Braethi (and Alliance) would probably take longer than the Diplomat's lifespan, given the existing cultural relationships. If you think it would be a good idea, I can expand the scope of the "Federation" epilogue to show that the Galactic Confederation eventually forms stronger ties with the Braethi and Selei, since some of the epilogues already cover events beyond the protagonist's lifespan.
3) Yeah, since the Braethi's government and most of their population has already been affected by the headsets, I don't think negotiating peace with them would be possible until unaffected people came to power, which really couldn't happen within the timeframe of the story. Hopefully this isn't too big of a disappointment. Again, if you think it would help, I can add a positive reconciliation with the Braethi to the "Federation" epilogue.
4) Hmm. This could be interesting, but I'm not sure I want to add side pages. For one thing, it would mean I probably couldn't get this published by the time I wanted to, for another, I was trying to avoid side information pages so less worldbuilding-driven readers wouldn't feel like they were missing anything. I might sweep through and add in a few cultural details here and there if you think that would help. And yeah, the races are definitley on the superficial side, since there's only so much time to explore the various cultures.
5) I was trying to do that with all the negotiations, so either A) You picked up on it subconsciously, or B) I'm not making it nearly obvious enough. (For example: I tried to foreshadow the Braethi's deception by showing the internal disagreements and tensions between Hessan and Neb, and I tried to show how paranoid and suspicious the Dek were so that the player could determine giving them space and offering them military aid would get the best results. The Selei were a bit tougher, all the options and their outcomes had a specific outcome and rationale that I could explain, but since the Selei are so reserved, I couldn't think of a way to explain it in the narrative.) I'll see how I can work that in with some of the other races, but since you're actually present for many of the first contact situations, I'll have to think of a different approach. I'll give it some thought. Let me know if you have any suggestions.
Things you liked:
1) I'm glad to hear that worked out. I was working hard to give them a distinctive voice, but I also didn't want to cramp the player's style.
2) Victor was probably the most fun to write. He didn't appear in my brainstorms at all, but I when I sat down to start writing, I realized the main character needed a boss. The fact that he's the only non-player character who stays in a major role in all the major pathes also made his various roles fun to explore. I'm glad he turned out well.
3) Stranger was a lot of fun too. I liked exploring the idea of a hive mind in a non-evil way, since most sci-fi tends to potray them as being evil and expansionist. He was both fun and challenging to write because he's speaking with all the intelligence, memory, and personality of an entire collective, but is also deliberately trying to come across as normal to humans.
-I'm glad that the concept of the Braethi was a positive. I liked the idea of the villains being the ones with crazy reckless technology, since in many works (at least, the ones I've read), it's the protagonists who operate in this matter.
-Glad to hear that worked out. I was really trying to avoid dragging the story, so it's good to hear it worked.
Once again, thanks a ton for all your feedback. This is immensely helpful, and I appreciate the time you've taken.
