Few other questions, as I was digging into the files. I'm sure you've worked on this, but I'm wondering how 100 turn strategies in the files actually effect the AI? It struck me that I'm often still in the colonization phase (often well after turn 100) with no need for much of a military unless I find myself right up against another AI. These plans seem to cap out at turn 100, and ofc well before that the AI turns its attention to a (generally) useless military build up of obsolete ships.
I'm still finding that the AI should really colonize more in the early game. It is so easy to outpace them, and even though they do start to colonize again later, its often too late to make much difference. Either that or fore the player to slow it down.
I noticed Missiles disproportionately effect military score. Build a few missile frigates and your score sky rockets, where as a few kinetic ships you dont see much of a budge.
I think the AI focuses too much on offense for it's ships. Often they are pretty much all weapons with a few token defenses. I love the changes to beef up defenses in general, but the AI ignores them for now.
AI seems to kinda have gone into a sleep state when it comes to other AI's. I rarely see them at war with one another, and never take planets from each other (unless by influence).
Still have not seen an AI build up anything other than economic/mining modules on starbases yet. Seems to be something that got broken with 1.4 by stardock.
I appreciate how difficult it must be to balance carriers. I wish we could have a separate hull size just for fighters, would be much easier to balance.
Overall, its amazing to reflect the amount of change even since I've started playing this mod. I started in 1.2xx and many amazing changes since then
I still think you should work on the incredible / godlike difficulty levels for us more hardcore players. I'm still custom adding in difficulty lines to beef up the AI, but I'm not very good at it yet 
Just wanted to add that the AI can be very strong if it gets a good start. I've seen it adapt to my attacks of choice (this is late game) and generally build up strong fleets and attack relentlessly in the late game. Its just that this is still somewhat rare (about 1/3 games) even with the bonuses I give it.
