but that argument doesn't work. I was about to argue that a magic sword IS more technologically developed than a standard one. Non-magic wins over magic according to the low-tech rule. It's the underdevelopment, not the scientific nature. Besides, my point is that the lightsaber may be magic, but it's magic CIRCUITS, made to simulate a sword. Circuits are higher tech than swords. The fact that the lightsaber should "trump" a normal sword is in fact an argument for the ninjas, since it's the underdevelopment that wins.
Beides, the jedi have more gear too. Luke has a blaster (a clear tech development over anything the ninjas have, even with their big automatic weapons), Anakin has a portable long range, voice activated communicator. Darth Maul has his repulsorlift bike and those spy drones. Even Yoda has a repulsorlift ride.
Looks like the Jedi are going down. Even if only those individuals go down, takes out half the jedi already. Then the Ninjas have numerical superiority.
