Chariots are quite good on this level if you know what you are doing. Chariot rushes can be successful on IMM. Warriors are crap though you can lose a chariot to one in a city as warriors have some city defense. Honestly, you can warrior rush an AI on Prince and below. Chariots and mounted in general also have the advantage of speed. It's my preferred method of warfare. Well, again my intent was to take Barc since it was just sitting there with 1 warrior and you had a couple chariots around. I lucked out on my chariots not really needing to healing. 2 Chariots survived Barc attack with 4 health and 3.6 health, so moved them up the road and Seville was easy pickings. Just so happened Madrid was as well. But you could also simply orchestrate a stronger attack building several chariots and then pouncing. As long as she does not have metals it should be easy even with archers. You just need 2 or 3 chariots per archer depending on if city is on hill or has walls. Pretty much any city with food I'm gonna build a library if nothing else pressing. In some cases like Chaco its for the culture too, but the city will make use of the library nicely with some cottages and running scientists. Your Philo, so any city that has the food to run scientists, you want to do that to get the gpp flowin'. Good question. Avoid trading for dinky techs like say Myst, Hunting, Archery(never trade for this ever) etc. Not a big deal on this level but there is a thing called trade caps. You hit trade caps and AIs stop trading stuff with you for a while (We Fear You Are Becoming Too Advanced). So I primarily look for gold trades, but I will trade for things like IW definitely., possibly Sailing. (On higher levels this idea becomes much more pronounced. You really have to think about tech trades and setting up good trades) Currency allows you to evaluate trades as well, as you can pair trades against their tech and gold. For example: AI has 30 gold. You match your Writing to their Archery +30 gold. They agree. Next turn. You match Writing to their Archery but they only give 10g. They are teching Writing for sure. I will trade Writing for their gold. I assume you mean a certain amount of unhappiness. Well, not really. Pretty much common sense here. First, you ain't whippin' off strong tiles like I mentioned. I don't mind stacking a little unhappy in a city. The issue is growing into unhappiness without a plan to use that immediately. That can be remedied by adjusting tiles - tile sharing - running scientists - or simply building a worker or settler. In other words, you can always stall growth temporarily to avoid actually running unhappy citizens. I do that all the time. I would continue with your game, but you can do whatever you wish. I'd continue expanding as long as there are good cities nearby, and I think there are.
