Well, I'd like to not trade anything. Archery is a so cheap tech. Can anyone see how many turns would it get to complete?
Actually, I've become less friendly to alphabet recently. The more I play, the less I want to trade. Well, it's always good to trade Alpha for IW. But IW is cheaper.

The only thing I like to get from Alphabet is the path to Literature and The Great Library. Besides that... Well... I'd never even bother researching the top path. It's pretty common seeing in my games that I delay Drama until veeeeeery late...
Well, back to the point: We'll have serious trouble trading with these AIs. I looked into the XML and they have the following attributes for trading:
LEADER_JULIUS_CAESAR
<iNoTechTradeThreshold>5</iNoTechTradeThreshold>
<iTechTradeKnownPercent>40</iTechTradeKnownPercent>
LEADER_BISMARCK
<iNoTechTradeThreshold>5</iNoTechTradeThreshold>
<iTechTradeKnownPercent>70</iTechTradeKnownPercent>
LEADER_NAPOLEON
<iNoTechTradeThreshold>10</iNoTechTradeThreshold>
<iTechTradeKnownPercent>60</iTechTradeKnownPercent>
It means that Julius and Biz will hit the WFYABTA soon and Napoleon and Biz will not trade anything if all the other AI's don't have it. Why I say this? Because they all are willing to trade something with us (So, the "we don't like you enough" isn't the reason they won't trade) and IW doesn't enable any wonders for them to be building. The only other reason they won't trade is Napoleon and Biz haven't yet met. Is there any chance of this?
