I've been scratching my head recently regarding AI aggressiveness. Supposedly it was fixed a little more with the last patch but I find myself coming out of a game with the same experience as before. I intended to come onto the forums querying this, but it seems that after reading a few other threads, the AI is indeed aggressive towards human players.

But I'm still gonna ask anyway because I haven't experienced it.

My experience with virtually every game of Stellaris so far is that the AI always seems very held back when it comes to attacking me. I usually play Stellaris fairly casually and often while working on something in the background, so the AI is often able to easily overtake me in strength, at least early on.

But I can count on one hand the number of times AI has actually declared war on me with no provocation (ie. insults or a lead on from a previous war started by me). And certainly, no AI has ever actually beaten me or taken me out of a game. This is over every previous game.

I find this weird because on so many occasions I've had a grumpy, very powerful neighbor next to me who by all logic should be marching his armies through my streets, but doesn't, at all.

I don't know about you but this severely takes away from the fun of the game when you realize nobody else truly poses a threat to you. Especially playing a "peaceful" empire with no intention of declaring aggressive wars, you find yourself doing an awful lot of nothing.

So question- has anybody else had AI actively go after them without provocation? Has anybody actually been handed defeat from an AI declared war? I play with high aggressiveness but normal difficulty, because it's painfully obvious the AI gets huge buffs on higher difficulties.

The AI nation description significantly affects their war mongering posture ("peaceful traders" "democratic crusaders" etc). If you get surrounded by aggressive AI descriptions, you need ample defenses alliances; if you're surrounded by the more peaceful types it's pretty easy.

The AI nation description seems to matter just as much as the actual relationship modifier, which means it has a huge effect on AI behavior.

In my current game though I'm surrounded by two aggressive hegemonic imperialists who are working together. I haven't quite finished the game, so perhaps something will change, but they just seem so... disinterested in attacking me, despite having very low relationship numbers and both declaring me rival. If I were one of them, I would have wiped me out some time ago.

My first campaign in 1.5 was the first time I actually got wrecked by the AI.

I had rivalled them, but only because they rivalled me first, and then I built a colony that blocked them off the hyperlane between spiral arms, so they declared war. I obviously had in my infinite wisdom failed to confirm that they were still "equivalent" in fleet strength before building that colony.

Their willingness to attack you depend on your fleet power. Twice in two different game, I lost half of my fleet due to engaging leviathans and immediately, my imperialist neighbor declared war. So, if you want to attack them, lose half of your fleet first. ;). Btw, early on, don't get cocky with the equivalent fleet power. You might simply have tech advantage (which is not worth a lot in the early game) and the actual different in fleet power could be around 500 ish.

But I'm not being cocky... the particular neighbor that I thought would be more aggressive is an advanced start AI with considerably higher tech and 12K fleet size, while I'm still sitting back on 3K. I curious whether the AI considers distance between them and you as the actual physical distance between borders or the jump distance to actually get to your borders.

The AI takes too much into account in my opinion. I've had 8-12 corvettes all game but not been attacked by a fanatical purifier because my tech was too high. If I get to the point the only things I can research are repeatable techs and i haven't built a single military ship for 80 years next to a fanatical purifier then something strange is happening.

I was only attacked twice, once for ignoring FE after they warned me consequence: humiliation and the second time was after I built a 20k fleet and rivalled the neighbouring federation and got the event fleet maneuvers on the border which forced me into an offensive war(?) after telling them to mind their own business.

I noticed that AI tended to be more agressive when using wormholes than Hyperlanes. Maybe it's just me but it feels like in Hyperlanes only games, they struggle to understand proximity based on lanes position.

I've certainly been attacked quite a few times by people who thought they had advantages. Just fought an early game war against an AI with only 300 more fleet power than me (c. 2100 v. 1800). The AI was too cautious and I was able to run around him and siege planets. But I've lost a couple games to aggressive AIs with the head start advantage.
