Wow. A compact, interesting RPG concept - spanning whole solar systems, condensed to some pages. I can see Dune and Warhammer 40K shine through. Having made a ttRPG myself many years ago, I know what work it is to care for all details, balancing and character generation. So I can only applaud you.
But, as it was submitted in a Cyberpunk GameJam, I have to ask: is it really Cyberpunk? You write that it is a "political sci-fi ttRPG"; yes, it is. The political aspect is rarely seen in these details in cyberpunk media, and cyberpunk itself often follows the motto "High tech, low life". Your characters, however, are "high-life", as they are governors, colony leaders, diplomats, warlords, members of the Nobility and so on. All this would fit perfectly in the Star Wars universe, for example, but less into the shady streets of a classic cyberpunk adventure. I wouldn't dispute that both can be combined but in its core, to me it seems less cyberpunk and more (very) far futuristic sci-fi like its role models or the Necromongers worlds of The Chronicles of Riddick. But at least both are dystopic views of the future. Well done.
