I have always really like the Dyson Sphere, and its mirror image the Antagonized Dyson Sphere. I'm adding support for Dyson Antagonizers so that the Dyson Sphere will be able to turn against you.
At the moment the Dyson Sphere works approximately like the AIWC Dyson Sphere did, and at the moment I'm coding the Antagonized version to be basically the same as the AIWC Antagonized Dyson.
As a reminder, the Dyson Sphere produces ships constantly at varying rates (they produce relatively few ships while the Dyson hates everyone, ships slightly faster when they like the player, ships much more quickly when they are trying to chase the player off the planet). Also sometimes the Dyson Sphere will do a Big Spawn where it creates a couple ships at once. Different ships are unlocked for the Dyson Sphere depending on the intensity of the faction.
The Antagonized Dyson Sphere will take its ships and send them toward the player's Home Command Station one planet at a time. The Antagonized ships will fight previously spawned friendly Dyson Sphere ships, and will actually stop to crush your defenses for each planet they attack.
This is solid and functional gameplay, but it would be cool to have them do "something else". Do people have any fun ideas of what else the Dyson Sphere (or the antagonized version) could do? It would have to fit in the general Dyson Sphere flavour (enigmatic, doesn't like anyone else on its planet, not particularly cooperative). Perhaps instead of a steady stream of antagonized ships, it should "save up" a bunch of ships, then release them en masse to help break your defenses? I don't want to change it too much though; the Dyson is a simple, solid piece of design.
