Like every time people have asked or said that in the past, I'm asking why?
You can just go a few hundred meters away from our infrastructure and then you have something equivalent to this. There's no reason to start over.
Fiah suggests moving our infrastructure to the new world. This makes no sense either, because it'd be the exact same as cropping the old world.
To get large biomes would be the only point I could see. But if you want that I'd rather set up a poll and find a way to change the world type of Blacraft.
In any case, I swear, forget anything about me throwing the old world away. We've spent 16 months working on it now.
No new world has anything which Blacraft couldn't have.
