Using default starter world settings, AI on challenging. Currently playing 3rd game. So far the AI hasn't been able to get out of the starting gate. In my latest, three of the four AI opponents have bit the dust, the first two fell in the first 30 turns or so. No idea what is killing it. I'll admit though that in my latest game I have packs of 'strong' critters roaming freely as well as three Ashawake level 15 'deadly' dragons. If they run into me I am reloading previous saved until they path a different direction. AI doesn't have that opportunity though. There are additional of those dragons sitting on settle spots. Now, I have avoided them like the plague, but id there are as many as it seems, then I'm willing to bet that the AI is waking stuff up by building too close and is getting eaten for lunch.
The other packs of strong are Iggy stacks, Earth elemental with earth shrills, and Air elemental with air shrills.
I have a total of four settles, building slowly and have just gotten to the point of being able to clear those strong packs.
Loving the new visuals. I absolutely love the studded collar.
