Rogue Trader
Core RulebookCore Mechanic
Roll d100 equal to or under a characteristic or skill after a difficulty modifier between +60 and -60. Each full 10 points under the target adds a degree of success, and each full 10 points over adds a degree of failure. Fate Points let a character re-roll a failed test, add +10 before rolling, or gain a degree of success. Spent Fate Points return at the start of the next session.
Best For
Groups who want a long campaign as the senior crew of a starship, growing a merchant dynasty through trade, exploration, and void battles in the Warhammer 40,000 setting. It suits tables that enjoy detailed d100 rules and want business ventures to drive the adventures.
Highlights
Profit Factor folds the dynasty's wealth, credit, and standing into one shared number that the group tests against to acquire gear, ships, and favours. Endeavours frame profit-seeking ventures as sets of objectives whose Achievement Points raise Profit Factor on completion. Starship combat divides each ship turn among the crew, with one Explorer manoeuvring, another firing, and the rest able to take actions such as emergency repairs or augury scans.
Considerations
Damage beyond a character's Wounds inflicts critical effects from tables organised by hit location and damage type, including permanent maiming and death. Insanity and Corruption Points build toward disorders and mutations, and a character who reaches 100 in either is removed from play. Gear normally comes from Acquisition tests against Profit Factor rather than tracked money, so groups that enjoy counting coins lose that layer.
