Yeah agreed, nukes really suck and the first two statements i agree with. However the idea of making a unit invulnerable to a nuclear attack is a little to far, and i think that the damage is just right. I do think that the radiation needs to deplete at a faster rate that way i dont have to drive units around it same with the whole radius idea.
Nukes are the one aspect pf this game that would force me to leave, I think. Unless you started in the very beginning, and are huge and making buckets of money daily, you're at the mercy of all these asshats who seem to have unlimited nukes at their disposal (it doesn't strike me as odd at all - not even in the least - that these same people all named after a certain real world rodent-run empire seem to play from the same house supposedly which is very convenient...what the hell...are the Goslings playing GT now?). These people can just end your game any time they want to do it.
If we're going to have nukes, then let's have an ultimate type of defense to nukes that's buildable in either the main town or wherever, and would essentially serve as a Patriot missile system, or some sort of Star Wars Defense Network.
Nukes, in my opinion, if used, do too much damage, destabilize the game and discourage two parties from engaging in conventional warfare for fear of being nuked...pretty much like they do in the real world, except that in the real world, most countries wouldn't use 15 nukes on Jawesomestan because the fallout alone would destroy their own country in a few months. Of course who wants to program for fallout, not to mention the inevitable public outcry that would essentially cause your national output to grind to a screeching halt? Not me. I couldn't program my way out of a wet paper bag.
