It makes sense either way!! We get that, but its what stays true to the games true aspect, and concepts. Its a game after all, so obviously saying that the earth is chunky and still round doesnt matter cause there is no such thing as a strict block chunk world either. Thats the point of imagination, and staying true to what notch initially created and would be all squares. But I am like a diplomat here, cause I see both sides really. The round sequence would work either way cause from afar thats what the minecraft world would like. If you were on the moon, MC's world would be just as round.
