I have to say, loving City States right now. So much conflict for so little effort.
Using Warsaw as my excuse to continually shoot the Ottomans with the glorious armed forces of the English Empire - they have nothing I need and Im not playing with Domination as a victory option so war for lulz is as good a reason as any.
Keep peace treatying with them every time they lose an attack on Warsaw, they then attack again while I cant attack them on Warsaws behalf (peace treatys cant be broken what?!), so as soon as the treaty is over, I hit them again with lots of arty and destroyer guns, and grind towards yet another city of theirs.
Its quite fun.
All the while the majority of my Empire is making cultural and technological advances towards the victory conditions.
