Add a new rule, “Emotions”:-

Each Crewmember has zero or more Emotions, tracked in the GNDT as a text string and defaulting to blank. Valid Emotions are listed below, grouped by their Nature, with each group listed progressively from High to Low.

• Angry, Stressed, Calm, Listless.
• Reckless, Careless, Cautious, Paranoid.
• Euphoric, Happy, Unhappy, Depressed.

A Crewmember may at any time give themselves any Emotion, so long as they do not already have an Emotion of that Nature, and that the new Emotion is neither the Highest nor the Lowest of that Nature. If a Crewmember has two Emotions of the same Nature, any Crewmember may remove the Highest of those two Emotions from that Crewmember.

If a single Emotion appears in more Crewmembers than any other Emotion, that Emotion is known as the Atmosphere; otherwise there is no Atmosphere.
