I consider RUNNERS to be a “space adventure” or “space opera” like Star Wars, that focuses more on the adventure, and less on the actual science of some other hard-core sci-fi stories, like 2001 and certain Star Trek episodes. I’m just more of an “adventure” guy than a “science” guy. So I don’t have much interest in heavily plotting my stories around the science and technology of how certain things actually work (IE inverse tachyon beams, chronoton particles, ship explosions actually not making sounds in the vaccuum of space, etc).
That being said, I do like to know how things work in my universe, without getting super-technical about it. So with Hamron’s body shells, it made sense to have the force fields work in a certain way and have certain limitations and “rules” to them.
