I'm starting to realize more and more the power of tech trading and see what some mean when they say it's one of the strongest multipliers in the game. In fact, in TMIT's last couple of Let's Play, he demonstrates pretty well how to do it and uses the diplo tech screen pretty well and quite often. I have to admit that up until now, I rarely looked at it (I check the relations and resources only). I think I understand what what the different columns mean: What the AI wants: Tech I have the AI doesn't have Will trade: Techs the AI has that I don't and is willing to trade with me Won't trade: Techs the AI has that I don't and won't trade with me I find the "Can Research" column somewhat confusing but that because I don't know the tech tree by heart yet. Are there any strategies when it comes to tech trading? I mean, when an AI is not willing to trade, I guess this is what is meant by a "monopoly tech?". How do you get the AI to change from not willing to trade to willing to trade it? Are there techs that I should research that would then cause the AI to trade the "monopoly tech"? Another question: Sometimes, people would say to research Aesthetics to then trade it for Alphabet or Iron Working. From what I understand, an AI will trade techs if they are of equal value. So why just not research Alphabet directly instead of researching Aesthetics? Is it simply because the AI doesn't prioritize Aesthetics so I would would be essential getting 2 techs (Aesthetics and Alphabet) by researching one (Aesthetics)? Are there other instances when I should be researching a tech so that I can then trade it with others?
