not sure if this'd count, and also nothijng's there considering the update came very, VERY recently, but that golden cube from the rimworld anomaly dlc has some serious potential. an entire colony of hardened warriors crumbling into thralls for an indifferent inanimate object, or even potentially a great and vast psychic superintelligence?
theres barely any rimworld in general actually, which is funny, considering all the psychic drones and psychic soothes and joywires and stuff.
