[@DawningAurora] Completely allowed! Mechanics, civilians (involved in things), engineers, designers, scientists, regular soldiers, officers, and more. The most limiting factor is just roles that can be included, like, no one needs to play a mailman or farmer. Pilots won't be the only ones with scenes as things like engineers and soldiers can assist in space or on the ground, on mobile weapons or equipment such as computers, com units, rockets etc. I'd love to have engineer characters who know more about the machines then the pilots and ridicule them for damage or praise them for finding new mobile weapons!
