Have you considered opening up the AI for a modder/contractor task force?

Hi, I can provide some late game saves if you let me know where/how to upload

Basic issue with galaxy AI I have seen is that diplomacy is not used by the AI even above turn 300 and when it has the necessary research capacity. Never seen the AI form a single alliance in 5 play-troughs, each with 12-14 AI civs and over 300 turns. Each time all my scores went through the roof research wise and then all the other scores but the AI is always more busy with waring with other civs instead of ganging up against me. Not saying they should all gang up against the player but at least a few alliances should be prioritized by the AI if it wants to avoid certain defeat at that point. There is no way mathematically it can avoid being defeated even the player does not do anything else in the game

Dropbox it is then! Please find my two Thalan late-games below:

Note that all CIVs are quite content living in the shadow of the player and warring each other with minimal success. Admittedly I have built a lot of diplomacy boosting buildings but if the AI wants to win it cannot ignore such huge advantage (it is basically insta-win if the player goes for tech and avoids major diplomacy penalties)

I understand it is hard to find the right balance so that the user is not always drawn into an all-out war (it is fun to play peacefully) but the AI could at least try to build alliances and not wasting time and money on fighting each other when they are clearly out-teched (and otherwise out-performed in every aspect)

Hope the saved-games help a bit

Something to note for the AI: It seems pirate ships attack the drones of planets which are automatically replenished due to a race specialty.

This might not be intentional as it serves little purpose. Doesn't really seem to hurt the player and makes the game more easy as it lures away pirate ships from constructions, freighters and the like

Shall I provide a save game for this as well?

Hi Frogboy!

Please find a saved game below showcasing some AI anomaly with transports:

On the top of the map Irridians are in war with the Altarians. As an avid supporter of the Irridians I have sent a few fleets to clear the way for their troops to the nearest Altarian planet. After having destroyed all enemy ships, bases and having waited for several turns now my ally is still not invading although it has several fleets containing transports read to go just a few clicks away

Update: After reload of the save game the Irridians did send one of the fleets with transports to the planet but sadly it was the one with the speed of 2 moves per turn. Considering that the target is undefended, no enemy in sight but my allied fleets and that they had another transport fleet with 7 or so speed this was strange. Did take quite a while till they got there. I now question if the AI makes better decisions when the game is loaded. Maybe it calculates its tactics from the beginning? If I reload frequently the AI plays better?
