So I've noted that whenever I want to sell strategic resources (and it doesn't seem to matter which one) I'll usually get the usual 3 flat gold and 6-8 GPT for 20 strategic. if I go all the way up to 40 (or 60) however, the AI will refuse to trade and will never give me anything. But if I go once more with 20, they will buy it again as long as they can (I think as long as they can keep it, even if they are winning +6 per turn of that specific strategic). That is, if I want to sell 60 of any strategic resource, I have to make three deals, one for each 20 for them to buy it. They will also almost always buy it, even when they happen to have plenty of it, is outdated or are getting a nice surplus per turn. A long as they are friendly/allies with me, they'll buy. Now the other way around, when I want to buy some strategic, the situation seems also a little bit messy; even when they are allies with me and have 120 of that specefic strategic, they will try to charge me something like 13 GPT and 10 flat gold. If I want more than 6-7, they will behave the same way as they do when I sell: they will decline the deal no matter what. I'd have go down again for 6-7 for them to sell me something. Is anyone having the same experience? As far as I know I don't have any mod that directly affects AI behaviour (I deactivated Real Strategy on my present game).
