v1.20, BM 1.01, 2nd new game. Discovered 10 AIs in the first game, but gave up when I got 10x the research of the next best race around turn 70. Started the 2ng game on Hard and Max bonuses, discovered 4 races so far at turn 40.
I like the new behaviour. Every race has offered me some kind treaty on the first or second turn after we found each other. And it usually either has a non-aggression in all systems clause or it is negotiable with 1-2 counter-proposals.
Now, I often get, on the same turn, a treaty proposal together with a counter-proposal to my own proposal. Not sure if the drop of mood I sometimes see after I only choose one of these is attributable to me not answering one of these proposals. Just to make sure I don't propose treaties on the first 3 turns after discovering a new race, they send their offer soon enough.
Also, I don't know if it's moddable, but I am still getting some weird proposals. Oh, far from the totally random ones I used to receive back in the 1.13 days, but still. For instance, is it possible to make sure that the AI proposes (and accepts) treaties that contain "both empires share resupply" and "both empires share repairs" only if bundled with the "non-aggression in all systems" clause? Because I am sometimes receiving the share supply/repair offers bundled with the "non-aggression in neutral space" clause which does not make sense.
I have tried accepting one, mostly since it came with the population migration clause. And sure enough, the sharing clause does not supersede the non-aggression clause, i.e. I still can't peacefully reach his planets to resupply.
Also, a bit besides the point, but the addition of pop migration to SE5 together with the AI's eagerness to sign treaties actually makes the game trivial (yes, even more trivial). Sign migration treaties with 2-4 races that breath a different atmosphere and voilą, most of the planets you can colonize can be undomed
. In SE4 one used to fight and conquer other races then micromanage populations with freighters in order to achieve the same result
. But please do not use this to make it harder for people to sign migration treaties.
