I'm hoping that the next expansion for AI war brings some of these features, since no one else is doing it, apparently. I really want to wreck the galaxy. Especially need planetcrackers.
Just checking: primarily that would mean adding planetary civs, right? We've already got fortresses in space and planetcracking. Or do the planets not feel planet-y enough for nuking to qualify? Or is it that you specifically want to crack the planets with the civs on them?
Planetcracking, having a planetcracker, would mean having the ability to actually blow up planets and presumably the life growing on them. It's a statement in a galaxy. It conveys meaning, has impact, awe-inspiring hellfire rained down on an entire civilization. As the earth is torn asunder, mountains crumble, oceans are vaporized, and the planet becomes space dust, scattering to all corners of the sector.
In short, it is made of cool.
What you have now is still cool, though. :-)
