You seem to have read a bit little and limited the scope to the single trope. Going down the rabbit hole of tropes from the basis of the
Fermi Paradox and the two types of alien, humanoid or not (guardians/goids), you will encounter what appear to be clear tropes and aversions; deliberately blurring the line of cliche A or B into all-new AB is still story being formed by the same tropes. I don't want to look back at this rabbit hole two years down and be like "yep, saw that coming" or "oh, it was both, not either or." I'd like to say "how did no one connect those dots" or "omg this is (&*^(* WOW!" I have patience to see it though before I assume. I could write stacks of episodic sci-fi novels off the pages there, so it worries.
TLDR lol@starfish alien pun. Please don't be using writers who read trope indexes/pay homage to tropes for all their inspiration. My grandmother could predict a Star Trek episode as it aired new, I'd like her current expectations for this game not to be met.
