To avoid potential out of context problems ?
Really, a lot of player might assume we'll be the conquistadors, I'm more inclined
to think we'll take the role of the poor aztecs.
Your theory is sound. Since the "winter is coming" phrase has been thrown around. it's safe to assume the Thargoids have some beef with humans. I suspect Jaques Station has something to do with it.
After all many of us have been strip mining many systems in the vicinity to Jaques, in what we thought was an empty sector of space. Perhaps we were wrong.
All speculation aside. if anyone encounters a first contact scenario. Kill them all or get the hell out of there and call for help. This will be a war for the species.
I call on all scientists to get ready to receive tissue samples, even from the scorched remains of humans who have lost their lives in encounters with the aliens. So as to better understand them. Hopefully we can engineer viruses and bacteria capable of reducing the alien population to a more manageable level.
Even zoo keepers can profit from this war eventually, once we establish dominance. perhaps the only way to witness them safely and preserving them before the more military minded extinct them.
Best case scenario would be to implement the more docile of the species into a slave class, if we can manipulate the matriarch to influence the young this is their only chance for survival. Punishments must reflect the confinement. If they rationalize like we do their history and achievements must be eradicated or at least misdirected to the credit of humans Worst case is their extinction.
