I'd actually like a terrain generation system that uses slopes like v20, but isn't just a looped map, but actually generated like MC
and for the assets, it'd be kind of like the newer duplicators/macro saver, but would be cool if it there was a zone specifically for making assets, either a new world accessed from a GUI temporarily, or in an ingame computer could be neat (probably wouldn't fit this style though, was thinking of it for other projects)
