So, a CPA is declared in my latest game. Fairly low difficulty game, High-AIP playstyle. 5/5 Chivalric/Fortress Baron Chivalric/Entrenched Homeworlder.
Astro Trains 10 on both. On an X map.
And I'm in the middle.
CPA was about a thousand ships. I'm going incredibly starship-heavy [ie. "start with Zenith Devastator, get no other starships as a bonus ship, and then unlock every single starship and build all of them" heavy. Not kidding, even Scout Mk4s for the counter missile coverage]. I laugh at it with my friend, and I leave the computer for about ten seconds to get a drink as the CPA shows up. I have Core Missile, MLRS, and Needler turrets on pretty much every chokepoint world I've got.
It was then that I realized three things, very rapidly.
1. AI 2 had sent its' Special Forces after my starship fleet.
2. The AI did not forget what AI Plots I had on.
3. I forgot that AI 2 had Hunter 10 on. So, as my fleet faced 5 H/Ks, I barely managed to retreat with minimal losses. Thankfully the disassembler guardians didn't show up, and I was right near a wormhole.
