[PvK]

I think the neutral AI just doesn't give Warp orders. It does give orders to move between its own planets, though. I'm not sure what its restrictions are about which ships and planets it can attack, however.

Seems like this would work better if the AI's used weren't neutral, but were full AI's. Then require all players to maintain treaties with each other, and perhaps to maintain no peace treaty with the AI's (except maybe their "own" AI agent).
