In the interest of conquering the whole galaxy, I decided to take on the What Memo challenge.
I haven't really been documenting my attempts, but I had to start here.
Because the AI just sent 13 raid starships on the least effective raid ever.
They started in Waco (top) and went clockwise around until they hit Cenow (blowing up the command station). Only 3 survived to make it to Yopar, only 2 jumps from where they started, and subsequently died.
At this point I own 14(15) worlds out of 120.
