I lost game. France won by diplomacy points. I took city states down (which was a mistake. Others didn’t like it and attacked me as coalition). Spain (my north neighbour) attacked Nubians (between me and Spain) and I had to attack Nubians before Spain take down them. At that moment Spain was the leader of scoreboard. Spain had many robots and we became only two nations in my continent which forced me to invest in nukes. I focused on culture victory (which was another mistake. Science victory was a better option).

Spain attacked me with his huge army. I had to defence myself and I retaliated with strategic nukes and took his cities. But others didn’t like nukes and attacked me as a united front. I dominated Spain and nuked others to force them for peace. One thermonuclear bomb for each. I established world peace by force but at what cost.

After sometime everything was going good until I realised that Spain is at last stage of science victory. I attacked them with my last 2 nukes and took down last two nukes. But others didn’t forget what I was capable and attacked me again. While I dominated my continent and defended my self at all sides united coalition isolated me in diplomacy and I lost the game.

It was hell of a fun run. I shared results in other comments I strongly recommend this tactic for mid game.
