this is my main world, i do have a bunch of different structures, I built roughly 75% of the structures which there are many, I did not build offset island, the rail road station, giant mushroom, funland 2.0, and if you can find the underground house near the main base (that too lol) but most of it i did build, i did lay down all the rails by hand which spider out very far. i would put credit but i really don't remember who made them. do note its 567 mbs when its un-zipped but it will give you a decent amount of fun, you can either travel above world or visa vee the nether i have ways to get around in both areas.
