Played a few more turns up to 325bc. On the whole it was pretty dull. Settled last island city. Workers built roads through the jungle. A few WBs and buildings got built (though not enough lighthouses).
Darius of Persia researched aesthetics before us. On the other hand we weren't planning on trading with him (Shaka's worst enemy). We got to aesthetics in 375bc, put one turn research into alphabet. Traded aesthetics to Jules for alphabet in 350bc. Put one turn of research into IW and made this trade in 325bc:
Tech trade table looks like this:
Our explorations have progressed slightly:
We've just popped a GM in Karakorum. Overall quite uneventful indeed. Still no-one has their hands full. However unlike some shadow games the Romans aren't averse to settling the jungle:
What to do with the GM? Having just got alphabet the GM can bulb currency (+1TR/City= +21 commerce per turn) or could go on a TM (trade mission). Trade Mission would likely be more valuable (certainly 900 gold, maybe 1100) but would take a bit longer (turns to travel to destination city then turns of deficit research) and I'd almost certainly be researching currency anyway. If it took 10 turns to get currency through TM I'd have lost 200 commerce through getting extra trade route later (20*10 turns). I'd also be further behind on my next tech (probably though not definitely CoL).
There's also the issue of the Roman settler. I've got a settler for Emerald City that can be settled this turn, this would mean the Roman settler would have to move further before settling a city which would buy time for Karakorum to produce the next settler for Banana City.
Astute observors will have noticed that we've just traded for IW. Do we have iron (given that we don't have horses or copper). Well actually yes:
That will annoy any AI spies sent on a sabotage mission

.
Astute observors with a good memory may also recall that this spot would have been inside capital's bfc if we'd settled in place. This may explain TMIT's ironic comment in post#25. So we've lost 4 hammers, I'd rather have wheatfish city any day.
There's one other unclaimed source of iron far to the south west:
Its a long way away and pretty vulnerable, even though its coastal I think I'll give it a miss.
Religions are a bit random, think I'll stay NSR for the moment.
As a discussion point I'm tempted to bulb currency with GM and settle Emerald City this turn.
Looking forwards there's lot of other issues including tech path and builds (I can now build granaries, axes, spears, swords and certainly need more than three workers)
