Yo guys. I've been thinking of a few things that are cool in my mind.
Some kind of new Sandbox scenario where "Dread Lords Strike"
One player (AI OR HUMAN) is the Dread Lords. They start with all techs researched, a class 15 planet full of Industrial Sectors and a few ships. They may not colonize planets nor create fleets. Their goal is to kill everyone else, everyone else's goal is to kill them, at which time the game ends. Or an option to continue like normal, going for the win after the Dread Lords' Defeat.
I can't mod, so someone else actually doing the modding would be great!
