So what if he makes it round? Theres always texturepacks durr
Texture packs my ass, I'm a vanilla person. None of that stuff that breaks badly without it. Even if it's just outdated texture packs.

He seems to only want it like this because removing straight line parts of a square moon wouldn't be as noticeable. But really, it's a terrible idea in general. Making other cosmic bodies round is a bad suggestion.
