Here's the story - Immense, 9 challenging players, etc. I'm playing Drath. The Terrans next door were getting too big and started dumping Influence bases in my space, so I built some heavy cruisers and decided to put them in their place. I made an extremely effective drive for Earth with a load of Transports and took over their entire core systems.
Unfortunately I didn't have the resources on nearby worlds to continue taking their remaining planets, so I bunkered down, built up the worlds I took, and let the influence of Earth flip remaining worlds. They were left with a handful of Class 8ish worlds (nothing bigger than a single Class 11, a couple class 5s, etc.) and I figured that they were done. I used my spies to look at their planets and found that there were nothing but factories, the occasional research lab or morale building, on the remaining planets.
As I built up a defensive fleet, I realized that near-endless fleets of Terran warships were pouring at the worlds I took, all being built on the few remaining planets they had. I was somewhat floored by this.
- The Terrans hadn't built a single economy building, and I took their planet that had the economic capital.
- There were maybe two farms amongst the 8 or so planets they had left.
- These planets were strict manufacturing centers, churning out endless waves of warships.
- I had destroyed all their own trade routes. They had SOME money coming in from trade with other races, but it would've been very little, as there were almost no trade routes amongst the other races. I had pretty much sent everyone to war against each other at this point so trade routes would constantly collapse.
How the hell did the AI have ANY money at all? They kept this up for several dozen turns, massive, expensive frigates popping out of worlds to try to blow me up. They showed no signs of slowing.
I was similarly struck by the realization that if I didn't have economic planets built, my economy would've collapsed into ruin long ago. When I used spies to look around, I realized that there were barely any enemy economic buildings on any of the AI planets - it was almost completely non-stop manufacturing.
What am I missing here? I heard the AI doesn't cheat, but for the first time I had my doubts as they seemingly completely neglect any economic improvement, but are able to churn out endless numbers of spacecraft.
