im not going to cast a vote on the correct "word" yet, but im going to try and inform the people in this thread who seem to be confused. there are 7 classifications of outward characteristics that AI aliens can sort into, alien races, of course, up to now, being randomized.
perhaps at game creation we could add our own ai nations but that is neither here nor there.
back to the point, this does not mean that the number of preset, whatevers need be 7! after all, id hate to have a preset mammalian race and no humanoid(mammalian) race, or vice versa. it could be less choices than 7, it could be more, but it has nothing to do with the number of classes, orders, phenotypes, whatever, in the game. i dont think at any selection screen you will see something like "7 fabulous choices!" why do i bring this up? well, to inform, and also to suggest that the term paradox settles on move toward something that could be seen as vaguely political, as in suggesting that you're reading about 1 faction and not a type of alien, like family or kingdom. after all, the way i foresee it(and i may be wrong) the only place you'd ever see this in game is when observing a species, in game or in the selection screen or whatever. in that case, something like "order: mammalian" isn't too confusing.
after typing this all out i decided that i love an idea somebody else had earlier in the thread. archetype
