Maybe it's just me but when playing solo vs an AI opponent, the AI likes to tease me by launching an attack on one of my worlds and sending a snarky message like "I hope you like the smell of rockets in the morning".
However, I noticed that it would send one Disciple-class ship to my most fortified chokepoint and say something like "Say goodbye to Maichan" or whatever. Usually, the ship would be space dust before I finished reading the message.
But when a fleet with 3 motherships and a ton of other cap ships lands on one of my production centers... nothing.
Anyone else see odd behavior like that? Aside from stuff like that, which is essentially flavoring, the AI is brutal and seems to play fairly intelligently.
