I'm not aware of any of this, nor the books or tv show, BUT
People have made Middle Earth before, so detail it has footprints of where the Fellowship went. They basically added a mod with a ton of new stuff to help make ropes and stuff too.
I have some worlds I'd love to make like that, big medieval city so detailed it has working sewers and everything, guards at every post, everything. I see other people with them, but I always get discouraged, as I forget...it's taken them 6-8 years to make those things. lol
