However, the AI seems to now have gone in the other direction. While as before, the AI seemed to hate everyone and always go to war (unless you pay them off); now it's the opposite. Everyone loves me. No one wants to fight... Initially, everyone has the, "we are very wary of you". But that quickly goes away and then they all just like me. They want to form trade agreements and give me money (even when only at +5). Even the Sluken like me (I am the Shandar)! This is going with Restless aggression level. The AI still seems to lack the "lifelike" feel that makes it feel like each race is different. These are just my initial impressions; maybe things will change over time.
A lot also depends on galaxy settings for aggression and what point in the game you are at (later game, things get a bit more cozy and then the more aggressive races get a little more active. Government type can also increase or decrease an aggressive race's tendencies (for example a Sluken Democracy, if near your Democracy is much less likely to go to war with you than a Sluken Military Dictatorship near your Democracy).
Also, the AI, even on Very Hard, doesn't seem to expand much at all. I'll try making them larger and see if that changes things much.
This is very unusual in my experience. How far into a game have you played? What were your galaxy settings?
If you are concerned, feel free to upload a save for us. There are so many possible galaxy setting combinations that it's very helpful to see a save anytime things behave differently from expectations.
