Best For

Groups who want a shipboard science-fiction sandbox with career histories and a working trade economy.

Core Mechanic

For uncertain tasks, roll 2d6 plus a skill and characteristic modifier to reach a target number. A natural 2 fails and a natural 12 succeeds when the task is feasible. Effect is the amount by which the modified result exceeds or misses the target. Advantage means rolling 3d6 and keeping the highest two dice.

The core uses a consistent skill roll against a target number. Depth begins in career creation and grows around ship ownership. World data connects travel and trade to the ship economy. Separate conflict and construction procedures add interlocking rules to learn.
