Well... If the AI ever gets an upgrade, I have an idea for a name.
easy --> normal --> hard --> unfair --> Cykur
I don't think the developers ever foresaw it would be possible for someone to beat nine unfair AI's.
I'm sure they will keep making refinements to the AI through the Diplomacy product cycle -- it is definately a lot better than it was before Entrenchment. Don't think I need it named after me...don't need everyone killing me all day long -- thanks though.
