Do you care about warmongering penalties? What about when you are playing a Civ like Macedon or Persia? Do you even attack friends sometimes if you feel like it? Does it matter even if it is egregious penalty? When playing Macedon for instance do you feel it best to wait for a casus belli? or is it too important to keep warring to reap benefits even if you attack friends and get worst warmongering penalties?
