Im positive Someone has experienced this Phenomenon, Besides me. But As chances are, most of you havent Ill exercise my typing Ability's and give 'er a whirl.
So there I was, Ghandi, in the 1920's. I was well into the Modern era, Just-made peace with the Zulu, Americans and less recently the Russians. I was Big, So big in fact, I was bigger then their Islands Combined. Then out of nowhere Russia Launches 2 Nuclear ICBM's Straight at me! Taking out some of my bigger cities! More over, The Americans and Zulu (who had both had Military Alliances against me with Russia) Declared War on Russia.
I, Driven by revenge, launched Nukes back at them. They desolated Russia, by next turn. (It would be wise to say this is a mod, self made, and with ICBM's having Lethal Bombardment)
I quickly went there and practically walked in Russia's cities. But I hated America, The sniveling fools where the only Challenge to My World Domination. In addition I had made lots of ICBM's in fear of not being able to conquer Russia's Cities, So, I foolishly launched them all on America. . .
20 years, and 10 ICBM's, Later Most of America was gone, and I was eying the helpless Zulu, When Out of nowhere what I call Nuclear Desert struck, I must have burned up the atmosphere with all those nukes
! every turn something along the line of 18 "Grassland turned to plains!" Messages popped up. With the occasional "Plains turned to Desert!" Or "Tundra turned to Grassland!" (I figure that I launched 18 nukes, hence 18 squares) Soon My civ was Starving And Rioting everywhere, Plus a blotted red sun was to the right of the unit commands. Has this happened to anyone else?
