1) We're desperate for a lot of things, haha. You may have a point with getting settlers out generally speaking. Possibly we should switch to settler now in Carthage and whip it with the overflow going into library, regrow on library and repeat (if lib is finished, substitute for granary or units). However, I'm not sure on the "western coast triple split", probably mainly because I'm not sure where you mean exactly. Anyhow, it looks awfully food-less over there. I do fancy going east, but we need some more scouting there. I'm not sure if we can afford to move one of the archers in the capital there. Well, maybe we just should.1. I think we desperately need two more cities. One on the western coast for the triple split, and the other to the east as a blocker. I think these land-grabbing Settlers would have to take priority over Workers.
2. We can run binary for a bit while we get our Library up, which means that I don't have to worry about tech' paths, as I probably won't get past Alphabet.

2) Alpha would be a good stop point anyway to see what we can trade with the AI and discuss about it. So I'd suggest you play up until that point (can't remember how many turns that is though).
