Oh dear. That's a shame. I think I've got about 20 odd turns left to get them to 75,000, and everyone else is building Spaceship parts like crazy. Izzy is also doing lots of business at the UN, although I think I have enough votes to ward against a win.
Gosh. Winning by culture on Standard is much easier. I know you have fewer turns, but it's technology, wonders, improvement, population that get you ramped up on culture, and those come way earlier.
I think they overdid the stretching of the goal. Something like 62,500 or something would have been more appropriate, I think.
Cheers.
