While we're thinking about victory conditions something I sometimes ponder is how to account for bad actions.
As an example a surface group in hostile waters sinks a neutral sub before getting a positive id. Maybe that sort of thing should be available as a victory condition for the opponent? Or maybe a neutral side could be triggered to align with another side, thus joining the enemy?
Or the scenario aim might be to defend a transiting surface group but not to escalate the strategic situation by taking out enemy bases or distant ships?
