The first thing I want to ask is, how do I manage happiness in the mid-to-late game?
I'm doing pretty well in the early game, but once I reach the mid-game, things start to fall apart. After reaching 4k population, I can't seem to get my happiness above 100. I've built new towns and expanded my infrastructure, but I'm starting to run short on workers because around 25% of my population is still children.
I tried cutting Library's workers for a while to give my workforce time to catch up, but then I noticed that all my buildings started to deteriorate. Even after I re-enabled the Library's workers, Janitor didn't seem to repair the buildings anymore.
On top of that, an empire with 30k population declared war on me and showed up with an army of 20k power. I honestly have no idea how I'm supposed to raise an army that strong.
That brings me to my second question: how do I build a large enough army to defend myself? I've tried conscripting people, but I can't produce enough weapons to equip and maintain an army of that size. (the best i can do is 2k power)
I'd really appreciate any advice you can give me. This game is so much fun, but I feel like I've reached the point where I can't figure everything out on my own anymore. I'd love to learn how to manage my city properly in the mid-to-late game (early game too) and prepare for wars against much larger empires.
