My relationship with P&C adventures is… strained. I often like the stories they tell, but their moon logic is too often too strong for my poor brain & patience, so I start using a walk through. With this game it was the same, but it was better than many other offenders, as i only used it a few times, so I consider it one of the better designed P&C games.
You play as the android Horatio Nullbuilt (voiced by non other than Logan Cunningham, the voice actor from Supergiant Games, voicing all those old gruff ones like Dad Hades or the narrator in Bastion), the last name is one of the great points of world building in this game. It describes by which other robot this unit was built. Some ancient robots are even called humanbuilt, after the semi mythical creator beings that apparently lived once in the ancient past on this planet. But Horatio doesn’t know his creator, hence Nullbuilt. He lives with his own creation and side kick Crispin Horatiobuilt in the airship UNNIIC and they try to repair it. Somerobot steals their power core though and so they take on the journey of retrieving it or finding a new one. This ultimately leads them to a city of robots, which shortly does away with silly questions like "oh no, does this robot have a soul?"and instead asks you the important questions like determining the parental naming rights between bickering robot creators.
While that last one is one of the few moments that lie more on the humorous side, the story of Primordia is in general on the serious side and in my opinion in the tradition of Isaac Asimov’s AI: it has a premise about how the robots work and tells a story around that. The melancholic atmosphere of this game is one part I especially enjoyed.
If you like a well told story about a society of robots more on the serious side, give it a try! It’s available on GoG, Steam and apparently also on iOS & Switch.
It has been a while since I played it, but I really enjoyed it and it didn’t feel too long. I loved the Canticle for Leibowitz easter egg too.
