Space Loss to Peter, 1760 -- Challenger Save.
Well, for a while there I thought I might actually have had a shot at winning this one. Happy to come this close on Deity though, I guess... (Still...

got to get smarter about some things...

)
I went for Diplo first and then fell back on Space after Qin vassalized half the world. Got the UN built in 1320 AD, but just couldn't quite scrape up the votes. Might have made it if Alex hadn't DOW'ed me (and my DP partners) in 1290 AD as I was at +9 with him before that. Arg!

[
EDIT: It took me two attempts, but replaying from my 1000 AD save I got the diplomacy victory in 1420. So close and yet so far... 
]
It was close at the end of the game too. I finished in the lead on tech, but managed Apollo badly and then just couldn't finish all the parts before Peter was able to catch up. The production capacity of the Deity AI is just scary.
I also got surprised on not being able to build the space elevator because of the latitude restriction. I doubt it would have been enough to change the outcome, but as a result I ended up with Great Engineers sitting around with nothing to do. Earlier I missed being first to Liberalism by one turn because of going back to get the prerequisites to Astro. One turn!

Frustrating...
