HypersomniacLive: Not sure I understand what you mean by the part I've highlighted. Going by post #2, it seems that scum have a choice in the matter. Are you saying that perhaps one or more scum have some sort of compulsion that forces them to sabotage? Could you please clarify?
I have chosen to see the crisis resolving in the ways it does in BSG and more so in Dark Moon where only the participating members can
influence it's outcome. In these games the event has some requirement that has to be met for it to succeed. If it's not met it fails.
In our case we are most likely required to provide certain amounts of STR and FIN. The obvious way to resolve it is to match the required amount against the total of the respective team members.
Here the two options come at play. The crew members seem to be passive, we always aim to succeed so our stats are always just added up in the pool (so far I haven't been asked if I want to do something different so my assumption is that we automatically add up).
On the other hand the scum can be either passive as well or active.
If they are active they may be provided with the choice of whether or not to try and sabotage the mission. First way that comes to mind is if they want to sabotage it their stats are extracted from the pool and the resulting total is matched against the requirement. If it's still met - cool for us, bad for the scum. If not - we fail and see what happens.
They could also chose to help out this time for Town points and add up their stats most likely resulting in a successful mission (even if no sabotage is attempted we still may fail if the mission's requirement is too high for the participating team).
Or they may be passive meaning they don't get to chose what to do and always subtract their stats from the pool. Their sabotage may still not succeed since a very powerful crew member may be able to come out ahead enough in the resulting total to meet the requirement regardless.
