This is with beta 5, but if given the occasion, maybe it could be tested with beta 6, I'd be curious to try it with a lonely explorer ship deep inside foreign territory.  The AI places lots of value on planets, starbases and ships, but it can't seem to realize how valueless something can be for me.

So, the Drengi surrendered to me and gave me their last planet, Drengi.  Drengi is deep inside ennemy territory, far, far away from me.  There's no way I can hold on to that planet, the Iridium Corporation will absorb it in a few turns.  So I traded the planet.  For all their credits, all their techs, all their resources, and a weekly payment of 600bc (wich the AI will lilkely never honor since it will go bankrupt).

I realize it's gotta to be hard to fix such an issue, but imho, it should be, at some point in the future.  The AI can easily be exploited with such foolish trade.  I know, shame me for abusing the poor little AI , but still...
