Concept: a game with one of those “ah, but can a robot etc.” dickheads as a prominent NPC, except over the course of the game their criteria for personhood become increasingly bizarre, until by the end they’re demanding things that aren’t applicable to any person who’s ever actually existed.
(Very near the end of the game, you encounter a minor NPC who actually does satisfy all of these esoteric criteria; they are, for unrelated reasons, an anthropomorphic chicken.)
