So what is an archetype? Or at least, what is an archetype as far as this thread is concerned?
Simply put, it's a 'base package' of a CAD for an ordinary, normal, not especially talented nor especially trained member of the given archetype. For example, the 'Normal Human' archetype will have very basic, very average stats for a human, with no major flaw, quality, skill or problem compared to other ordinary and average humans. It is in no way meant to be used as a 'one size fits all' set of stats, as much as a fundation to build upon, as in actuality, almost everybody is better and/or skilled at some things, and worse/untrained at other things. Archetypes as I use them are essentially a guideline to know how good or bad a given being is compared to an ordinary, non-exceptional member of their archetype.
That being said... well, that's that. Pretty much.
Nothing is impossible, it just hasn't been done yet.
NOTES: Humans are the quintessential, basic species in most known settings. While they have no inherent special abilities, powers or exceptional skills and potential, humans are also characterized by a lack of disadvantages that many other species may have. So while humans may not have the strength of bears, the claws and fangs of tigers, the speed of a cheetah or the wings of a bird, they have complex brains and reasoning capabilities, excellent societal potential, high manual dexterity and opposable thumbs and a bipedal locomotion, all allowing for complex tool use which allows humans to evolve and adapt. Finally, they have a very complex language use compared to animal communications granting them a lot of potential in socializing, which many creatures lack. While this all may seem trivial compared to supernatual or more advanced species, it does set humans head and shoulders above countless others.
The CAD above is for an ordinary guy with no skill, training or out of the ordinary potential whatsoever.
