Games Workshop does not own the copyright on nearly-dead-warriors-entombed-in-exoskeletons. Nor did they invent the idea of the nearly dead being sustained by cybernetics, or of using robotics to assist those of limited physical ability. We all are inspired by things.
It's especially odd to talk about about "Warhammer" or "Starcraft" as if they are managed by a single human, when in fact all of these worlds are written and envisioned by a multi-generational army of creative people who are all drawing on sources to come up with ideas. Are all of the employees of GW who write about dreadnoughts plagiarizing the employee who came up with the idea?
