Warlord just to try the new techs etc. out.
I've conquered the world on Kal-El's huge world map on vanilla CivIII on Deity level, so I don't think I'm all that bad. That was a conquest victory as the Iroquois (Space Race and Diplomatic conditions turned off). Score was around 16000? if I remember right. Finished it around 1850 AD. That was an epic game. Spent the last 400+ years in constant warfare as a Democracy. Engineered a Russian/American nuclear war (the two superpowers ahead of me) by giving the Americans nuke technology, uranium, aluminum, rubber and oil. The entire continent of Africa (where they were located) turned into a nuclear waste zone while I picked off the weaker Civs like Persia, Greece and the Zulus. Persia had given me quite a scare with a couple large conventional army attacks, nearly stealing my oil; I ended up nuking the armies with a tactical nuclear strike on my own soil!
Then the Russians turned on me, tried to nuke me (SDI, woohoo!), so I nuked the hell out of them (Africa becoming more of a desert, but I cleaned the pollution up with armies of Russian slaves) and finished them off with MA's and artillery. Finally I finished off China who was in South America with a couple of strategic nuclear strikes and massive armies of MA's and paratroop landings.
But I'm going easy on myself here until I get the hang of the tech tree and what wonders are really worth etc.
Oh, and the moral of the above story is that you CAN win a nuclear war, even on Deity. You just need the first strike stockpile and SDI.
