Suppressing the target location's culture centers entirely might be a bit much IMO. After all the opponent does need some counter(much as all races ahve Aux government to partially defend against novaliths).
how so? First, if I just shot your planet with the DE and it blew up your culture centers, that won't neutralize your planet unless I have a very strong culture presence already. Second, won't Aux government provide the same defense against the DE?
If the Deliverance was to destroy media hubs in one shot it would instantly turn the weakest superweapon into the strongest one.
I fail to see how. It takes alot to flip a planet with culture. If I shoot my DE at your world, and it takes out your culture centers, you've got time to rebuild them there and you can spread them out so as to minimize the loss... I've had the AI 1-shot'n my planets with Novaliths recently; that's a hell of a lot worse. Yeah, maybe I should have gotten the planet hp upgrades and put up a SB with aux government, but I lost the planet now, and cant do anything till the radiation wears off and I can retake it.
furthermore, nobody says it must be every culture center at the planet. it could be 1 or 2 every shot if that is somehow found to be overpowering.
