Hi, thanks for playing, and for your feedback. Replying point by point:
- In the future I plan to have military units without a barracks suffer attrition and die, but for now they will hang around until killed.
- The only ways to reduce population are to create settlers, or kill them.
- In ancient Mesopotamia wood was too rare to burn, other fuels would be used instead (dung, brush). I've had some good suggestions around coal and charcoal (which could be produced from wood) for further bakery and bronze smelter upgrades, but they seem low priority for now.
- You can trade wheat, is that not enough?
- You can send multiple settlers, and have them join the settlement once it's founded.
