Silly. That is an extreme example that no player in their right mind would do in the first place. Or do I have to spell it out: the AI acts in its own interest now assuming the player is acting in his/hers.
Extreme or not, it occurs, and demonstrates there's a problem. Same with the planet going for 280 BC. The AI "assumes" nothing, nor does it particularly act in its own interests - its a set of algorithms designed to initiate specific responses and actions depending on a large number of variables. I'm sure the code is fairly complex and the developers have all kinds of fun tweaking it ( I would! ). This last tweak was a little too much, and that's IMO.
And its incredibly dumb to expect the AI to give equal trades or a 'fair' price. Given circumstances, techs can have variable values, and any benefit for one player is in the end at a disadvantage for another. Any good player knows this.
Do we want the AI to act more like a player or not?
I didn't claim the AI should be "fair" in trade - but it
should be affected by the variables I listed earlier (attitude, diplomacy, close to getting conquered, alliances, established treaties). As for cheating, lets say: it was obvious the AI has some benefits in those areas. Of course it needs them.
Lastly, I don't consider this thread "idiotic", nor have I leveled charges of "silliness", "dumb" at anyone, or insinuated someone's a poor player. Try to provide cohesive and sound arguments in the future without resorting to such.

If the changes made please you, revel in them, and have fun! I can tell you the adjustments made to technology trading are being met with broad dissatisfaction. That's fine, too - the old saw about "pleasing all of the people all of the time . . . ."
Ok. Let me be more precise so as to avoid more strawmen that have taken from an intentional misreading...the AI acts in a way MORE consistent with its interests in terms of tech trading now than it did before the patch. Of course I wasn't claiming it wasn't perfect, and there are some sweetheart deals it should take, though no good player, AI or human, would make those offers in the first place, so I still don't consider this an honest argument. The second part of the post wasn't aimed at you, btw, but by another post that claimed the AI should have made a trade for an equal level tech.
And I generally believe that a lot of the complaints in this thread have less to do with wanting the AI to be better than in wanting to continue to cheese it. Because if the issue is challenge, the AI is surely better now on the whole than it was before the patch.
