It has been a fun challenge, but it also makes any passive diplomatic playstyle impossible.
I would like it much better if there is an option to adjust the aggressiveness of the AIs.
That's the point. Base game AI will let you turtle and wont ever threaten you in any way.
Turtling is impossible in this mod. You'll get steamrolled. I've still had game long friends, but they are generally not neighbors.
