My two cents
Is is no cities or no military? I always thought it was no military but.....
Barbs cannot pop if you have no military, I saw some Realms Beyond players discuss this.
But DO NOT move the worker onto the hut, since if you build a city you can pop the hut too. I think the terrain S and SE of the mountain are most likely forests (I can see a little of their edge from the screenshot). The mountain also seems to be the starting point of the river. Even IF we do spot good terrain to the south, it will take at least 2, maybe 3 settler moves to get into position. We SHOULD move the worker onto the northern floodplains tile, just to see if there's any bonus resource up there, like wheat or something, and in any case be prepared to irrigate the floodplains.
Our initial start is fairly good, with four flood plains visible, two capable of being worked after settling, and three capable of being worked after cultural expansion. Plenty of mountains for future shields, and we can use the forests (I hope I'm right!) to the south as immediate shields. I think we can probably micro this city to be a settler factory, hopefully a 4 turn one or maybe a 5 turn one.
What's barbs set to? If it's not highly aggressive, we can simply do a farmer's gambit, otherwise we should send warriors to escort, and then our flood plain food advantage may not be so advantageous.
We should probably do max on pottery, so we have a granary to take advantage of the extra food. Or maybe if we're shield starved and barbs are aggressive, we will need to build warriors then settlers, making the city like a 6-8 turn settle/warrior pair fact, and maybe a granary isn't so useful?
The GL would be highly useful on this difficulty. We have the beginning of the tech tree to literature, so maybe we should do min sci on writing then max on lit? Or if the AI is really slow, we might even be able to grab philo...
One last note, we should found a coastal city asap, build a curragh, and get us some contacts!
Hope I don't sound like I'm rambling and that this post is too long!
