Swords are also hard to control with a mouse and keyboard.
Imagine yourself surrounded by a transparent sphere, on which you can paint a point and a line. Where on the sword is that point? How does the point/sword travel along a line?
This is not easy to solve.
What happens if you shift your perspective after a sword attack is drawn? Can you amplify it by looking away? Can you arrest the motion, by looking towards the executed sword motion.
Modern VR motion controls are better. Much of the innovation in physics based gameplay and things like sword mechanics is happening in VR, because the controls are accurate, expressive and low latency. Wii had the idea but lacked real tracking (a smartphone accelerometer can do Wii gameplay better than Wii).
VR controls are exausting, almost like a real sword battle. Real innovation for gaming is when the controls do not exaust you.
What may look like a working system (touch-control) either vannishes after a while (novelty factor wears off) or turns into yet another stone held in a relaxed lapgrip..
