For the most part, the rules assume that entities of the same scale—human vs human, starfighter vs starfighter—have been in conflict. However, it’s quite possible you may find a human staring down the barrel of a tank, taking on a starfighter, or attempting to change a civilization. When two entities enter into a conflict with one another, the differences in their scale come into play:

  • When interacting with a larger scale entity, you gain a +2 bonus to your roll, and incur a -4 penalty to any shifts which result.
  • When interacting with a smaller scale entity, you incur a -2 penalty to your roll, and gain a +4 bonus to any shifts which result.

These modifiers are cumulative with each step. It’s possible for a human to try and talk an entire planet (+6 Planetary scale) into a trade treaty, with a +12 bonus to the roll and a -24 penalty to any shifts generated.
