This one is probably going to erode my interest in Galciv3 much more quickly now.
I've got two different games where I initially met the Altarians and/or Drengin, and I offer Open Borders to them as soon as I meet them. What can I get for that? 40bc, and that's it? Nope--how about EVERY SINGLE ONE OF THEIR SHIPS. So I initially meet the Altarians, and I get a 2 colony ships, 3 constructors, 2 survey ships, and 2 trade ships. For OPEN BORDERS. What's more: what impact does that have to his and my Administration? I had 3 administration before the trade, and I have 3 after. I can go to town with every civilization out there who doesn't value their ships.
I realize this problem can be easily worked around: simply don't trade for ships. But when I have to force myself not to do that, that takes away a lot of the fun for me. It also reveals that the ramifications of Administration have not been fully thought through.
