Where does that come from, i can remember only one map with an universal cannot be won seal.
It's ofc not from NC but Charly peninsula vs. paradise land Monty.
Didn't
@drewisfat win that completely legit with no reloads? Granted, map knowledge and multiple attempts, yes, but if we're talking "no idea how a map is from t0" then plenty of them should be unwinnable, or have win chances so close to 0% even with perfect play that they may as well be.
If we're REALLY talking unwinnable, Lain's
Tokugawa isolation certainly takes the cake, because every single AI runs away with the game and you can do
not a single thing about it from t0-t125 at the earliest, not to mention you have a really garbage island to work with, which has astoundingly almost 0 redeeming qualities. Because the biggest "landmass" is actually split into two, I suspect the AIs run away so much because there's immediate contact but
everyone gets intercontinental traderoutes instantly due to there being one tile of coast splitting the main continent (and, like, Bismarck/Asoka/Jayoh have seriously strong starts). And then, of course, there's Mansa, who will trade everything he has away and then promptly peacevassal to 15-city Sitting Bull. Most of the time, everyone will get optics before you even have a chance to meet all 6 AIs, you'll be beaten to circumnavigation, and Bismarck will get 1000AD infantry while Joao blazes away to superconductors and plastics by 1400AD. Even if you tech and whip and invade perfectly, there's just no way.
I actually managed to beat the game, but by going further than I had ever before in reloading. I turned "new random seed on reload" and then
reloaded an early save 4000-5000 times until I got a gems pop on my single mine. With the added commerce and happiness, I was able to be slightly faster to optics, leading me to actually be able to trade that just a little bit. Then I invaded with cuirs by reloading until Joao/Asoka didn't go rifling, and then reloaded every cuir fight until I won at 10% odds all the time. After capping them both, it was pretty straightforward, but up to that point you would've had to have astronomical luck to even land before almost everyone was close to assembly line and stuff.
