Wu Zetian and Sejong. OK, the latter is sorta understandable, but please for the love of Buddha or whatever, STOP spamming my continent with your underwhelming cities and throw in "R WORDS BACKED WITH NUKES". If you want to attack, JUST DO IT ALREADY. They have all the city-states except Ragusa or some cultural ally of mine on my continent, they have naval forces patrolling the north and west/east, they even have a small number of units and also the cities to base them to launch attacks, JUST START ATTACKING ALREADY.
... so I have reason to use my 22 uraniums, but digressing...
Both are so from another continent, both are some sort of runaway with Wu being the largest, AND both do not absolutely want to fight each other despite Wu maintaining the lead in everything.
This is the first game where I feel very, very, very, very, very personalized to start using nuclear missiles to delete all their cities sans the wonder-spammy ones (Seoul) from the face of the map.
