A somewhat serious suggestion. Can we have some planet destroying weapons? You know, like the Death Star's superlaser :p
I'm not asking them to be combat worthy, perhaps even just plain useless or impractical. Like, I don't know, something needing 80000 tons of space, short ranged, and using 5000 energy. Something that would truly require a stupid amount of resources to build, and that would be worthless in combat and so brought in only after you completely smash the oppositions.
The reason for this suggestion is that I want some ways to RP the complete annihilation of an enemy NPR. I find that being forced to conquer them all is NO fun at all. Surely I should be able to kill the evil, nasty, enraged aliens who never wanted to talk with me right? Why MUST I be forced to conquer them?
