Reconsider the labels 'strong' and 'weak' for scene outcomes in favour of 'upbeat' vs 'downbeat'
The outcome we currently get are not really strong or weak in themselves. They are derived from strengths or derived from weakness, yes, but that does not make them strong or weak.
The problem with calling an outcome a 'weak outcome' is that it sounds like a qualitative judgement of the narrative. If we say, for example, that a film has a weak resolution, that's a criticism. We mean that the resolution is wishy-washy, poorly handled or incomplete.
If 'weak outcomes' were retitled, players might be more keen to embrace them and the interesting narrative complications they offer. To that end, I suggest retitling 'strong outcome' and 'weak outcome' so that the outcomes better reflect their content. There are several ways in which this could be done, e.g. 'light' versus 'dark' outcomes, but I suggest 'upbeat outcome' versus 'downbeat outcome' would be suitably neutral terminology.
