I always felt there was a lot more to learn about the Thargoids, and about the Guardians and how the two overlap.
But I also understood, back in the earliest days after their appearance, when FDev said it was basically up to the players how Thargoid stuff would go down, that it was always going to end up in pew-pew's.
I remember the devs talking about the first time an Interceptor was released into the game - some players set out to destroy it immediately, even though there were no game mechanics for that yet at the time…
…and so out of all the possible interactions with this alien species, all the routes ongoing encounters could have taken, it did lead to combat and conflict, leading up to the invasion story arc of the last year and a half…
…so, even though it has been interesting to follow this fairly epic narrative the last while, with the final chapter grabbing much attention as the conflict plays out at last, I’m hoping interaction with an alien species will explore other options when/wherever Thargoids inevitably reappear again :]
