Hmm, that is odd that they would call it all "coding" (although that term is already overused to the point of meaningless so I am not too surprised).
I would have thought that character writing and in-game world-building writing would be about the same as other kinds of fiction, just with some differences to support interactivity (although most games' stories are on rails, anyway).
Thanks, and I hope that we can play test this in a few weeks. Really, aside from these movement consensus issues, the last remaining work before that point are a few UI perspectives (inventory and crafting) and then connecting the lower-level pieces (cuboid generator and network stack).
