Hey T2008, thanks! I'm working on updates for the interiors first and will try to make an update for the village exteriors afterwards to make it compatible with the others, then I will be releasing much more.
As for sci-fi, I definitely want to make some Sci-Fi tileset further down the line, first I'd want to release a lot more content that's cross compatible with the others but who knows, if inspiration strikes I just might do that in-between as well. :D
