Just a heads up...
Itza, and most other lizards, love to cast Rite of Primeval Glory (I think is the name?) -- the one that summons all the dinos -- as early as turn 15-20.
First off.... gd.... that's.... borderline unfair to fight against that early.
Second... it's crippling them.
They can't actually afford to maintain that army for very long at all, and as soon as they run out of money they wind up suffering a blow-back collapse as everyone just stomps their now undefended over-spread-out land claim from the dinos. TBH I'm not even sure how they afford to do the rite in the first place that early. Is it reduced cost for them or something?
Regardless... it's both ridiculous to fight against that early and it's hurting them.
Maybe consider changing it a bit for the AI? The AI is also prone to spamming that rite as much as possible... and even later on when they're in a heavy war it's more often a hindrance than help after about 5 turns since the AI isn't very good at managing its finances.
Just giving them more money is NOT the answer, mind you. Please don't do that.
