With this i mean as a battle system, does any story ever go in depth as to how the force works, the length to how things like controling object or any special kind of abilities inside the force only certain kinds of people can get? The films extablish that force sensitive beings can sence other force sensitive being if trained enough, besides their lightsaber skills the Jedi have superhuman resistence and increased reflexes above normal humans, with the gesture of their hands they can create force push's and control object to their will. The Sith have the Jedi's skills and are also able to force choke and create lightning with their hands. By using using force choke Darth Vader seems to be creating an invisible force hand, with this in mind wouldn't he also be able to create other invisible things with the force, like a force spear, an invisible force preson controled by the user, or even a giant force punch? The next thing is lightning, if they can create this, would they be able to create other things like fire or water? And since lightsabers are made up of some force powered crystal wouldn't someone be able to create a weaker spear ray together with the powers of lightning? I'm not sure if this has been shown anywhere else but in the cover of Dawn of the Jedi they seem be able to creat power light balls (DBZ style), those powers could be quite usefull. The last is the power to control objects, they probable don't work on the human body but does it have a range or maximum of weight? When two force users fight each other do they spark any kind of power to their surroundings that enables each other to use the oponent's clothes to choke them to death? These are just some questions, maybe they have been answered in the EU, or maybe they haven't, either way i think this is something i think should have been explored as they're the basic rules of fights between force powered individuals.
