So I've recently returned to this game because I got an email about helping out with beta testing as the new DLC is approaching. I've been enjoying myself playing SiS as always, but I ran across a scenario that I've never encountered before which is causing me problems.
To start off the game I freed some human slaves from pirates and made contact with their colony. I set up an embassy and saw they would agree to join my empire fairly quickly. As soon as I generated enough influence from the embassy I spent it to integrate the humans into my empire, leaving me with 1 influence point. Since then I've established contact the other major empires and I've realized I have no way to conduct diplomacy with them. I can't establish an embassy with any of them since I lack the influence. I tried briefly looking through the new tech tree, nicely done BTW, but nothing caught my eye.
Please let me know if I've missed something somewhere, but is the only way for someone to generate influence through embassies? If so, my game is finished diplomatically which is sad because the Orthin seem to like me and I was going to work with them against my hated cousins, the Ashdar Imperials.
