So I recently got back into AI War. I redid the tutorial since I was rusty and then jumped into a no-frills 80 planet game. I made a number of strategic errors (mainly taking too many planets) but was doing all right--I don't know if I could have won in my circumstances, but I was holding up and I felt like I had a reasonable chance at taking out at least one AI homeworld. However, I encountered a superterminal along the way and thought I would try to exploit it to make up for all that AI progress I had incurred. This was rather experimental, since the superterminal's description left some matters up to interpretation, namely the precise nature of the increases. I fortified the planet to an extreme extent with a mobile builder, positioned my entire fleet of over 2,000 ships, and then built the military station.
This was my final moment before unleashing hell.
We held for a long time, and while the AI reinforcements were increasing at a
clearly rapid rate, I wasn't prepared for what would come next. The growth of the enemy made them unstoppable, and they finally took out my command station. My fleet continued holding, but attrition was wearing them down and I decided to have the remnant
make a break for the adjacent planet I controlled, as I had already prepared some defenses there as a fall back. I had a self-cloaked Raid Starship IV standing down at the edge of the superterminal planet to take down the superterminal, but I hesitated to cast the elimination order, seeing that my AI progress was still falling though my command station was destroyed.
Then the exponential growth of the enemy jumped to insane levels. Suddenly I was in the tens of thousands, in seconds more the hundreds of thousands. And then... behold.
That's right, over a million. Their number continued to climb at a faster and faster rate, and then the game froze so that I had to close it through the task manager. It was mercy at that point.
So yeah... An interesting experience, and a memorable way for my first official return campaign in AI War.
If I were to make a suggestion about the gameplay from this, I would recommend capping the AI reinforcements for 'active' superterminals at some point. No maximum combined with an apparently endless exponential growth (I'm not sure whether this was exacerbated by my command station's destruction or not) seems like it can't be stable, and I think at some point the endless reinforcements are so unstoppable that a cap would not hinder their defeating the player.
