I could easily align the world against the Zulu and exit with a diplomatic win, but given that I can make the run from Fission to space researching every tech in 5 turns or less, I have probably a better chance of getting the fastest space win as I do fastest diplomatic. So we bury the vote.
In 1305 AD, the Zulu finally decided to try to do something about my advantage:
I was surprised they took this long to come after me - guess they were distracted for quite some time by Babylon's few island cities. But, the Zulu picked the worst possible time to attack - right after I got mech infantry, and they're still a tech away from tanks. Even cavalry armies aren't going to scare my fortified mechs.
That said, though, the Zulu did still have several dozen infantry that I had to fend off with arty and tanks. I did pull a Leader to get to build the military small wonders. I went as far as capturing Atlanta from them (it's the "12" city-size number visible under the stack in that picture), but then they would talk so I just took peace right away.
Nothing else worthy of note happened. Space Race Win in 1490 AD. 5224 points. So much for a beyond-Deity tough game.
