Heck, my space opera is based entirely off of bad world building tropes taken to their absurd extreme.
You know how a monolithic culture tends to be unrealistic? That in real life, nations and societies and races have a broad sweep? So, just saying, "This is a warrior race" is bad world building...cause...no race is just a "warrior race"
You could have a war LIKE race, or a militaristic one, but even then, there will be dissent within.
So, I took the idea of monolithic races and built an entire universe around it. In this universe of mine, the end result of technological evolution is a society that dedicated itself ENTIRELY into one Aspect: Warrior, Workers, Thinkers. And in the Empire (There's got to be an Empire) you have the Primes for each race, who are on the top, and the Vassal races who are way way down at the bottom. Enslaved, basically.
And so the Empire finds humanity. And no, its not what you think. Everyone always guesses that humanity didn't gain an Aspect. Well, they are WRONG. Its just that our Aspect has never been tried before.
We're really...really...really pretty.
Our entire culture is focused entirely around being as gorgeous as humanly possible. And as we are the only race that does this, we are instantly vaulted through arcane and ancient Imperial law to the status of Prime, completely upsetting the political balance of the galaxy.
Hehehehe.
Oh, also, my story is about archeology too. the main character, Zap Quicklaser, is an archeologist who travels to dead alien worlds to find their artwork and ways of expressing beauty. Its his personal quest.
