I have to say that I really enjoyed some of the themes in Primordia.
In particular, the theme of the clash of philosophies, and giving each philosophy fair hearing.
I know that other themes mentioned included decay, Horatio's lack of understanding of his own origins, and religion.
I was curious about a slightly different influence, the names of the cities. Metropol is Greek, derived from Mother City. The developers said that they thought of the council as Greek gods, and that would make MetroMind a sort of mother, as the only Metro-X on the council. This puts MetroMind in a very different position compared to the others on the council, who don't have such a personal connection to the city.
And while Metropol is Greek, the other cities, Urbani, Civitas, and Municipa, are all derived from Latin; indeed, they are all grammatically correct Latin words. Was there thought in making the other three cities from one background and Metropol being something different? Does this make those cities Barbarian (i.e. non-Greek) cities?
This was just something that struck me as I was playing the game, and I'd be curious to know what the answer is.
