I just played a game with the 4-10 build, it seems good! My only gripe has nothing to do with those changes, it's city-strength being too low when unfortified.
England ambushed me when I moved my army and navy to attack Germany (in like 2 turns lol) and took good advantage of both a tech advantage and their UU! That said, I wasn't expecting to loose my second largest city in literally
1 turn. I had fortification in it and I thought they should give me at least a few turns to move some of my army back home to garrison and defend. No such luck lol. Meanwhile my most recent city (with only walls) is still standing because I have a single crossbowman in it. I am a bit surprised to say the least. Should an unfortified city with a castle not be stronger than a city with walls and a weak defending unit?
Regardless, this game had two clear leaders: China who combined the strengths of their UB and UA with a lapiz lazuli monpoly. They hopped from wonder to wonder, taking an early lean and maintaining it - capturing cities belonging to both Egypt and Persia. Wu Zietan's army is double the size of most other nations XD. The second being Korea, mainly because they were the only founder on their continent! 6 founders on my continent lol and I still managed to convert Sweden and England to my religion which I am proud of. That said, Korea only gets stronger over time so there two are both forces to be reckonned with. Predictably Austria who had a lot of space to themselves started quiety but become a significant force over time thanks to their UA. Egypt started strong but I think their glory days are coming to an end. Btw my income is negative because I traded Korea 124 gpt for the tech Chemisty, because I could. The next turn he kindly gifted me 1200 gold! Thanks pal.
I was able to move up the ranks slowly, razing one of Germany's cities to give my friend Persia a bit of breathing space. I was planning to liberate a Persian city from Germany next, but England did well for a civ in last place and took advantage of my forces being out of town! You can see both cities that I lost and while I can easily recapture one of them it will have lost a lot of population and buildings by the time the war is over which hurts. I don't expect to keep either of those island cities! I guess one thing I am grateful for in this context is coastal cities getting supply from lighthouse and harbour.
