Playing this at the moment. I have a comfortable lead in science, I think I'm almost an era ahead of the next civ.. But still, it's already turn 312 and I haven't even built the bomb yet.
In my game Shaka didn't manage to kill off Washington, though he did feed Cashmir to the fishes. I have been paying Shaka off since I met him and he really loves me! Just now I gave him a measly sum of 200 to send him off against Washington. I think he'll be my attack dog from now on.
I took 3 cities from Korea when ideologies kicked in the first time, left him with one. He still got eliminated though, very recently by Washington. That's kinda what triggered me to send the Zulu at him.
Hoping that this will be my first BNW science victory ever, unless I stumble over something unexpected
[EDIT:]
Right, won this a while ago but only now got round to uploading the pic
It took a while, but I'm very pleased as it's my first science victory ever. Zulus ended up mauling Washington pretty badly, the other continent is pretty much all colored in white now. Always a good thing to have Shaka settle on the other side of the world ^^
