I kind of like the fact that the crisis has limited impact. It's important narratively, but if it was always bringing you down to the same level, it would be more frustrating than exciting. I had some that hit me relatively hard - ending antiquity with negative GPT, grinding my science and culture to a halt, losing a town or two to low happiness, spreading plague through all my towns and killing off end of an age productivity. But their malus doesn't carry over to the start of next age, regardless of what they do, so you will still start strong.Which means the anti snowball effect is way too weak. Bigger powers need stronger crises.
The real problem is the fact that the difficulties don't scale right - I want Immortal AI in the exploration to be tougher competitor than Immortal AI in antiquity, to match my snowball. Give them bigger force multipliers to Science or Culture, force them to always build their unique districts correctly so they get to benefit, or just rubberband their production pace to ours. I don't see their production numbers, I won't notice if their suddenly plop down universities in 3 turns instead of 7.
Also, I never let them get that far, but I saw others report they don't actually go for win conditions. As in - they would get 15 artifacts and just not build World Fair. I actually think it's a valid approach for something like Governor; they are meant to be a colour more than a competition there. But Sovereign and above, they really should gun for them the moment they unlock them. If I pick higher dificulty, I obviously want challenge all the way through.
