Just what part of Nuclear bomb don't you or other people understand? Why have it in the game if it's a glorified fire cracker? A nuke should always be devastating. IT's a game ender, a super weapon. Also why have different nukes? You do realize that the reason space programs started to exist was to develop better technology for ICBMs. An ICBM is basically a space rocket with a nuclear warhead, so I see no ready why there should be 2 or more different kinds of nukes. The only nerf the nuke needs once we get planet moving back is a nerf back to its original state were it could only reach parent, sister and child celestial bodies, so there is a reason to move your planet. Also we need more mechanisms that work that way (maybe SXX can be remastered so that they can only move that way but are strong enough to tank umbrellas), because let's face it: there is no reason to move your planet if it achieves nothing more than a change of position of your planet.
I agree that nukes are too expensive for what they are. One missile doesn't kill the Commander, and the area of inflicted damage is pretty small but the launcher and the missile are axtremely expensive.
I love nukes atm because you definitely don't need to use them, I hardly see them used. In fact yesterday was the first time I've ever used them this patch, and the first time I've seen them used. Nukes aren't easily summed anymore at all, T2 is just too expensive to make it possible, but as a helpful point of this it also means anti-nukes are hardly built which means you can build a nuke and deal quite a bit of damage. Nuke balance is pretty perfect as of now.
I use them when the game gets too big. Nukes are good to shut down enemy Halleys or to remove some vast defence line so my Infernos roll right into your sweet spot. I believe there should be two things done about Nukes: 1 they shouldn't be as expensive as halleys because they do nowhre as much damage as Halleys do. 2 I'd love to be able to target orbital targets with nukes. Because massive Anchor defence really has no weakness. if you want to remove them at all you need to build hundreds of Avengers which is not right. There must be some kind of weapon designed just against anchors. Maybe some super slow and heavy vehicle with low rate of fire but big damage that can shoot to orbit or something like that.
