I am a novice French MG but I positively love the Rogue Trader RPG.
I could consequently not resist organising a campaign in it.
I decided to serve my PCs a nice little low-tech planet to begin with. A medieval planet quite densely populated. The planet has a big potential with a lot of rich metals to mine but suffers a high risk of rebellion against the planetary local royal family. A version of the pre-revolution France during the 18th century.
The initial mission I had prepared for the PCs was to make a deal with the local royal family: we save your fat rich asses from the crowd, help you to keep control of the planet and you allow us to mine in return. I had planned the population was too large for them to fight against, even with a futuristic armoury, their personal troops were too few.
The PCs arrived at the main royal palace. The situation was tense with a large crowd surrounding the palace. They met with the local planetery king but decided he might soon be too hungry. They left him at the palace, with various promises of help and future business together. After that, they met the main leaders of the rebellion and made the same promises.
They came back to their ship to organize the distribution of food and blankets to the main cities of the planet. The food and blankets were contaminated with all sorts of diseases. The diseases had been carefully selected by the Mechanicus PC: a nice cocktail of smallpox and measles adnd others, relatively easy to cure for our own people who would sooner or later be in contact with it but lethal for a medieval population without basic medical knowledge. And the viruses were chosen/modified as not too fast to have the time to spread across to the population easily.
They spent several weeks following the distribution to repertoriate the best locations to mine. Also time to let the diseases spread and see the results. After two months, I had decided the population was reduced by 5% in the main cities of the planet.
They were very happy with the result and came back to the local king. They said they had called some deleveries of weapons for him to help him fight the rebellion, only to gain his trust and exterminate his own family with a kill-team some days after that.
After some more months, the population had decreased by 10%. The local population was too desperate with the diseases. The death of the king had left the leaders of the rebellion without a common enemy to rise against. The PCs encouraged them to fight against each other. They provided with some basic and scarce military equipment to play with against each other.
The PCs started to build mining facilities as far as possible from the plain cities to keep a low profile, begin to cash in and assess the progress of the diseases and civil war.
What advices would you give me to continue the campaign?
Let me specify I love the gothic feeling the Rogue Trader but I am not found of Chaos. I like to keep xeno-contacts as a minimum. I prefer intrigues and dark schemes Game of Thrones style. As my sadistic PCs do.
