Well specifically Goblins live in a world where the book "Leviathan" is true.
While I thank you for the compliment, I haven't actually read, or am even familiar with, every book ever written. I'm guessing you mean the one by Thomas Hobbes?
"Magic is fine if that's all you can come up with, and it ofcourse functions as an all-encompassing handwave in a fantasy setting. I wouldn't call it a thought-provoking mental exercise, but you are correct in that it's there, it irrefutably exists as an explanation for whatever you want it to explain away, much like mud exists"
Well you explain how a stationary civilisation without farms is capable of living off of only meat without magic.
The same explanation as to why the Suggestions Forum exists, and why I keep suggesting: ToadyOne isn't done yet, and I trust he'll have done an exemplary job when he is.
"As a counter to your argument, why shouldn't goblins be able to have advanced civilizations? Even ones which are in some ways superior to the other sentients?"
They definately could. I just think it is a leap to call their civilisation all so advanced just because they are still around.
I may be making a leap, but it isn't purely based on their existence, alone, and my explanation entertains me better than "They have a lot of sex, and are really pissed off about that.".
"I've already mentioned that they commit extremely threatening, aggressive, and immoral acts against the others, so they wouldn't lose their "evil" status. It just makes them a much more interesting, deep, and viable, threat and challenge"
Actually their infighting may be their greatest asset to their immortal, baby booming, society. It is a way that only their greatest warriors are still around. Any leader they have would be a great leader.
A large gap can exist between being a great warrior, and a great tactician, and the difference between one and the other often is the number of years of study and experience. War is where great leaders go to
die, not to survive. Particularly when the battles being fought are constant, internal, and petty, and political assassination is rampant, which it likely would be, in the environment you suggest.
Fast turnover produces poor leadership, because those leaders have less time to learn from their mistakes, pass on their knowledge to future generations, and even to earn the confidence of the ones being led--which isn't insignificant. Alexander the Great (who's father was assassinated, possibly by Alexander) was extremely well-educated for his time, and a genius tutored by a genius, and left behind a vast empire at about my age--an empire that quickly dissolved into massive civil wars, after his death.
The Greeks, as advanced as they were, although their doctors and scientists were held in highest regard practically everywhere west of China, although they continued to produce some of the toughest, finest soldiers in the Roman Empire, although they held the secrets of the most devastating weapons in the Byzantine arsenal, never again became an independent superpower.
I always assumed that Goblin technology was given to them either by spoiler or a continuous stream of great leaders who were able to unite them from their crazy infighting.
If that were so, they'd never have the sheer quantities of arms and armour they equip themselves with. There's a reason seiges are considered a great source of raw iron. If they are simply despoiling it, then who else is out there, churning it out in such mass quantities?
It's not the dwarfs or humans, because it's narrow, and it's not the elves, because it's iron. No reason to consider the kobolds, among other reasons it's too big.
And if there is a fourth option, then why are they such good crafters, but such poor soldiers, that the goblins are taking it all away from them?
As far as goblins being immortal: If the ones we encounter had lived long enough to finally grow tired of neverending youth, lust, and power, in an environment of continuous battle, then wouldn't they be nigh-unstoppable juggernauts, legendary in every fighting skill? Shouldn't they be the ones hewing our poor dorfs down left and right, instead of our champions slaughtering them, en masse?
