Can we discuss underground nukes

Wondering what everyone's thoughts are?

I knew this going into the game I wouldn't care for them. I like the blackmarket in general, but no other item is quite so game changing (maybe claims). The nukes should be super expensive, as they can turn someone prized tile into just another low yield tile.

The AI isn't too rough with them, but I basically turned many of their high/med yield water tiles into low yield, and it was pretty punishing on the economy.

I find them a bit permanent considering the rest of the black market weapons you can use.
