I played around with that map, and managed to make something of it. I call it "Whack a Mole". It is the exact same map that van posted, but i relocated, and changed some of the planets. I also added a pir8 base

I intentionally made the jump distances very long so you can somewhat prepare for the mayhem to come

If someone is willing to host this ill send it. I still dont reccomend this for Multiplayer. Its just a for fun map.
In the one game i tested. The Medium AI did pretty much as i predicted, and went straight for my capitol. The pir8's attacked right about at the same time, but their base is off to a distance so it took them a while to reach me. After the AI's initial attack it will split up its forces, and attack multiple worlds. Watch your bounty. There are no choke points here to save you

I took over 1/2 of a "spiral", and let the AI keep attacking. Planetary defenses, and garrison fleets are a must have for this map. You can see the pirates coming from a mile away (this is intentional). They will hit you pretty steadily, but you will have time to prepare for them.
