Wrap-around maps suck

Yes but the maps that wraparound both north-south & east-west do NOT simulate a globe. It simulates some weird geometry that'd give you a headache if you physically saw it in all its dimensional glory.

Actually, the geometry isn't that hard to imagine: it's a torus - something like the surface of a rubber ring (with or without the duck head; it doesn't change the geometry much).

Still, I'd like to see a decent explanation for why the world is like this (it can be a "fantasy" one, but still...)
