So a bit of diplomatic news this turn - Rego has accepted a NAP until turn 250, in return for us providing Open Borders to him for that period. A great breakthrough!
He's sending us Banana as well, and I've offered to send him some of our resources when/if he needs them too. Earlier on I was pretty dubious about dealing with him, but he seems to have become a lot more pleasant to chat with recently. He at least seems to have lost the attitude of fishing for information and then trying to avoid providing it in return. (Hopefully he turns out to be more trustworthy than my initial perception of him. Does anyone know if Rego has broken any NAPs in the past, incidentally?)
Anyway, there were a couple of main reasons for approaching him about a long-term NAP. Firstly, if we're going to be attacking Luddite at some point then we want to be sure our eastern front is fairly solid. And secondly, as I'll elaborate on below, I'm more and more frequently getting the feeling that Plako is distancing himself from us.
While Rego has (apparently) been becoming more friendly, Plako on the other hand appears more and more to be giving us the "cold shoulder" lately. It's mostly not anything specific that he's saying towards us - it's more what he's not saying. Conversations between us over the past 20-30 turns have more and more often consisted of us parting with information, and Plako saying "thanks" but not doing much else. Case in point, he's declined extending our NAP to turn 220, which seems odd if he truly appreciates our partnership and still views us as a long-term ally.
I mean, I know we've moved into the #1 spot recently, but when we originally made our arrangement he was far and away the #1 civ. I thought our arrangement was to support each other as two of the top civs regardless of who specifically was ahead at the time. However, it seems Plako was apparently only happy with a "partnership" as long as he remained the #1 partner - which is a bit disappointing.
Our relationship with him isn't entirely unsalvagable, but I get the feeling more and more that it isn't worth continuing to try. It's really stopped being a relationship of mutual trust now that Plako's philosophy towards us seems to have shifted to "take everything and give as little as possible - preferably nothing - in return". If that attitude changes, then things could still potentially work out between us - but it isn't looking that way at the moment, unfortunately. I guess we'll see. At least he's still NAP'd until T200 regardless.
