You've got to be kidding?!?
I've sat on the fence for about a year and finally ordered this game early this morning, and now I find out that the diplomacy options in the AI (such as not respecting boarders via colonization of your own planets) don't work??
Cripse, there was a similar problem with Civilization 2 in which allies still woulnd't pull settlers out of your territories after telling the ally (via diplomacy) to get out/off that I recall never being fixed... this was a frustratingly near game killing bug, one that I thought would have been fixed by now with so many patches to this game.
I came here to ask on the board which Version of SE 4 Gold came with the game, but man, this is a bummer to read.
