So this is my first attempt to see a large stack like that in action:
Here are the galaxy settings:

This is the stance at turn 235:
https://www.dropbox.com/s/a3ezc311adu6xzw/Galaxy.JPG?dl=0Haven't seen any indication of fleets amassing more then usual:
Humans (bottom left) only have a single fleet consisting of 1 Heavy Cruiser, 2 Light Cruisers, 4 Scouts, 2 Troop Transports and 1 Colony Ship. The other AI opponents seem to have similar fleets with one exception: An Ashdar Imperial fleet has been sighted containing 15 Light Cruisers
Played the game as a pacifist, no war with anyone so far and also the AIs themselves didn't seem to get around fighting each other.
The problem seems obvious:
- Sparse systems means, the AI cannot expand fast enough. I would have though that their fleets will still build up, but they do manage to throw them away at "Monster nests". Eventually they might still pile up but probably need to increase difficulty to the highest level so they get enough resource handicap (as they are very slow in colonization)
- Starting location: Player has started from the middle of the map. I do love this as a starting position, as normally it is more difficult, but in this case it just enables the player to colonies the whole galaxy from a prime location, while the AI is limited by distance of stars and it shortcoming:
- AI does not utilize Outposts nor Lane Amplifiers. Thus the whole Galaxy is ripe for player conquest. Normally Marauders would break the player but I have modded them out. This normally gives the AI a big edge, but in this case it just removes the one force holding the player back
Thus this game in won in around 300 turns and if the AI gets an additional 100 turns or so it might start building up, but that will seem irrelevant from a game perspective as it is over at that time even when playing as pacifist.
The issue I see with this scenario is more with the map layout and AI behaviour.
Solution is obvious:
1. Slightly decrease median distance between star systems so that the AI can expand
2. Let the AI build outposts to systems where it cannot colonies so it can expand further
Next, I need to increase to maximum difficulty and remove the mod on Marauders though I suspect this will again cut back AI progress as I have seen in previous games
