What is your favourite change that Vox Populi made? Mine fixes my biggest gripe with vanilla Civ V - the happiness system is reworked and wide empires are viable. It feels much more like Civ IV, where good city placement and growth are rewarded. The AI is also surprisingly ruthless. If they sense weakness, they will attack, including each other. I've played through a few ancient/classical eras now and they've all been a mess of wars. Just like real life I guess. So much fresher and more dynamic than vanilla or Civ VI.
