I think your interpretation is pretty legitimate within the "text" of the game. I just didn't want to be turning people off for the wrong reasons!
Finished the game 2 days ago, enjoyed it immensely. Considered reviewing it but I have far too much work on my hands right now, and a pre-Christmas trip coming up.
I have to say, the story was very well down, reminded me of a number of things. I liked it from a narrative stand point in that it basically mirrored the Fallout: New Vegas narrative: you begin with the death of the PC, who loses something to his killer. You have to track the killer down to the big city only to find yourself engaged in something much larger then the personal journey. You did it very well.
The character had a lot of pathos, and the setting was excellent. I actually wish someone would make an RPG in the setting, because just imagine the possibilities of a robot protagonist. Code and programming changes, or body modification offer a PC limitless possibilities of development and character progress. But regardless, the setting was magnificent. I liked the world without humans, yet the very human characteristics of the bots.
There was a bit of Nausicaa (the Miyazaki film) in there, the giant warriors scorching the earth, the onset of social breakdown and apocalypse. Very well adapted post-apoc tropes.
Without hyperbole, I can say it's objectively the best game I've played in 2012. I enjoyed Sleeping Dogs immensely as a fun open world arcadey game, but as far as story, characters, setting etc go, Primordia is the best of the year for me. It was a release which basically saved the year, as far as I'm concerned.
I also liked the puzzles, all very logical with some divergent paths, ie: Gamma, allowing for interesting endings. Most all of them were solved without the usual inane adventure game logic that brought us the cat hair moustache, and were straightforward in a cryptic way. Crispin being around to help was good too, though. I did fall back on him a few times for hints.
