There’s a lack of consistency sometimes :(.
Hard to complain about but in my games, I tend to get too powerful for things like landmarks and anomalies to be annoying (and the grail is an anomalous site iirc)
Also, one thing, not at you @Adam_B but at everyone, is that if you let the game progress to the late game, e.g. turn 80 plus, which is best done by having a very large map and hard AI settings, then the AI will start building and modding t3 and t4 units, and will usually outnumber you and will pose a challenge.
I think the sweet spot would be to bring that t3 and 4 wave forwards, ut there are AI mods that have managed this, I think by adjusting the resources the AI gets.
Anyway, my current Pangaea map is on turn 104 and I am fightng a war on 3 fronts, because I was closing in on a domination victory and the remaining AI got angry about it.
It is possible I could lose because the bulk of mya rmy is far to the east, where the 4th AI just got crushed, but my capital and main provinces are largely undefended. I have some 15 stacks closing in on me from various directions, but strong militia defences and a small mobile army in the interior should be able to firefight, while my massive (8 stacks I think) army in the east just turns in and destroys my enemies, from right to left.
I just had an epic fight where I won a defence with 8 Bulwarks (with the autonom self repair module) and 3 ramjets and 1 Vanguard plane, a Baron and some other stuff, held of a Syndicate assault led by 2 Zeniths. TWO.
It was glorious!!!
