I have, so far (I haven't read it to the end, but I'm close) one objection on Tales of Gor. (As an aside, do you know how often I have that few objections? It's an amazing feat that Desborough's book only provokes that few objections from me).
What is that one thing that I disagree with?
"Only the Panni** have systematized unarmed combat. The rest of Goreans rely on (natural ability)". I might be paraphrasing it slightly.
But this contradicts the books - in many, many places.
First, it is known that even peasants practice wrestling. Wrestling is always the first systematized style to emerge wherever humans live, but rarely remains the only one, unless the practitioners wear heavy armour (not the case on Gor). And given how many empty-handed styles have evolved from the use of weapons, it just makes no sense to me.
Second, the fighting slaves are mentioned to be "the real masters of unarmed combat" on Gor. Who trains them? (Hint: probably warriors, if they're lucky). And I can't believe the Caste of Assassins would have overlooked the use of such techniques to quickly subdue and kill a target that's hard to reach with weapons - say, a rich Merchant.
Third, Tarl and others repeatedly show quite high levels of mastery of the unarmed combat in the series. Here's an example I found in Magicians of Gor.
"I seized one of the lads by the wrist and, drawing him quickly across and about my body, and over my extended right leg, flung him to the stones, where I held him, my grip shifted now to the palm of his hand, his wrist bent, far back. He screamed with pain. Another fraction of a hort, the least additional pressure, and his wrist would be broken."
That's a move that's well-known to everybody who has ever trained in martial arts. But I don't remember Tarl having been a fighting slave - and anyway, he was doing such moves after the first time he was on Gor, while exiled on Earth.
Another example is at the end of the books where an Earthman brought to Gor obtains freedom (after being a Fighting Slave...sorry for not digging the exact title, but I can guess it was Something of Gor).
There's a moment when a group discusses killing a man empty-handed. One of the men gathered says something like "maybe, but only if you're very strong".
An Warrior corrects him: "It doesn't require strength, just skill".
The former Fighting Slave merely nods and confirms.
Thus, I'd conjecture that unarmed combat should be an option for both Warriors and Peasants, not to mention Assassins (and former Fighting Slaves). Though of course, weapon skills should be higher and more valuable - but one can hope the fighting system itself would take care of that!
That aside, I admit I'm tempted to produce a table for Gorean Chess. It sure seems to have...unexpected possibilities!
*Well, technically, I know exactly how much it's worth - just check the price on Drivethru;). But if you plan to run this game, you really want the setting book.
