Cohon gets you 1 extra trade route. Calendar get's you 3 decent commerce tiles. You have 2 luxury resources you could of traded for. I think the cow fish site should of been settled sooner. With so much jungle early on many of the early cities looked marginal. If you wanted to settle the cow/rice site that makes tech decisions a bit harder. What were the best techs to skip here? Pottery and cottages seems quite important. That and making most of 3c coastal tiles and financial trait. Tiny maps would probably make this slightly easier albeit keeping up with ai techwise might be more challenging on a jungle heavy map. When an ai has a free settler and is limited on land it stops any real expansion. Agree 5 workers with 7 cities seems low. Especially if you are farming plains tiles. Yes always have a plan and play the map. Aesth is always a good early trade bait.
