My relative powerlevels are usually quite low since I always prefer development in front of warring. And thus I never use leaders like Shaka, Monty or Gengis myself and thus usually have one of them neighbouring me *sigh*. And therefore most of the time I would not want them to know my powerlevel. By having more Espionage points than them and denying them the knowledge of my power, will that make them hesitant to attack me? Any idea of how much would be enough? Is it enough if they have a higher espionage cost than 100% against targeted civilisations? Is this a worthwhile strategy so long I try to keep the diplomatic relationships decent with the suspects?
