'Roleplaying Emotion helps you to understand the character’s emotions within the context of the story goal, their personal goals, and their motivations. When this are going well, the character will express things like affection, contentment, happiness, hope, and respect. When things go poorly, they’ll express anger, disgust, fear, sadness, and shame.'
Having read the above blurb I expected a mechanic that took in game events and helped determine the character's emotional responce however there are no rules for this at all. It's a little tough to unravel and it took a while to realised all it is is a series of extra tracked stats that define the characters emotional state but no rules for what modifies the stat values.
The descriptions of emotions, their consequences, and how characters enact them are ok and the choice of stats seem to be broad enough to work.
