Many players may not think this, but I view Dark Spire as the closest to AI War having a plague.
Especially when you have it at 10/10, its release will determine the course of a game. It is possible as a human you cannot survive it. But you may. If you do, then it is up to the AI to survive it as well. They do not always.
The "actor" who best deals with a 10/10 dark spire will win. As it should be.
God(s), I love the mechanic.
