There's custom entities, custom bosses with cool mechanics, custom weapons including 3D weapons./guns, custom morphs, custom armour, working furniture blocks, many building blocks, survival & multiplayer compatibility. Re-added structures from the original (not lite) version, but they do not generate naturally. Scroll up for a list of the structure names. Use the /structure command or a structure block to load these structures. I figured i could just add back the structures from the original version just for fun :D
