Its "open world" but the buildings arent built like Rust, and the gathering and such is all done by AI. You will literally be able to ride a horse down a trail and see the AI gathering wood, iron, ect in spots designated by the owner of the local town or what have you. The buildings wont be like SKYFOOORTTTT. It will be actual buildings, floors, roofs ect. Actual structure, with a World of Tanks type of strategic map where kingdoms fight over towns.
