Insane World Difficulty...

Is it even possible to survive this? Tried it just for laughs and, well, got curbstomped by the nearest wildland. Couldn't settle anything or build anything that would last more than a few turns. Didn't even meet half of the A.I.'s let alone fight any of them. High difficulty A.I.'s cancel each other out, high difficulty world seems to be a whole different story. Basically buried alive by the stream of monsters. Awesome experience.
