I like being able to buy enemy colonizers when they are approaching high quality planets in an area I have claimed as my own. I could see making it a bit more expensive though.
PogueMahone, that is an ingenious exploit. From a personal point of view, how would you like to be one of the colonists who is notified right at the time of planetfall, "We just got notified from headquarters, we've been sold to a race of hairless apes." I don't think that would go down well. Viva la revolucion!
if they take away all my exploits, I am going to have to find new ways to beat the AI on godlike,
Ah, FrancoFX, you will have to figure out how to be ever more clever.
But Aerez summed it up nicely
Ya all of the diplomacy AI is super duper stupid at the moment, and the devs know about it.
The current system of buying and selling ships appears to be just a placeholder. With continued feedback and suggestions from us customers, the developers will make it better. Else we will play Civ V or Railroad Tycoon or Barbie's Nails instead.
(hmmm...perhaps a counterbalance would be the ol' double cross. The Drengin ambassador asks, "Could you do us a favor and purchase 20 of our ships for pennies on the dollar? They're older and we find that their maintenance is a bit high. We'll even throw in some troop transports. It will be a win win situation. We liquidate our inventory and reduce our maintenance costs and you gain a new fleet. C'mon. It will be good for all."
Then, once they are well within your borders, the ships mysteriously disobey your commands (if you are paying attention to their movements, that is...sometimes you have so many ships, they are hard to keep track of) and congregate around your richest planets. In one fell swoop, they capture your industrial centers.
The Drengin ambassador then comes back and corrects herself, "Oops, I meant to say, it would be a Win-Win situation for us, not you. Lose lose!"
