An open world survival, where your objective isn’t just to survive or complete contrived quests. You have a main general objective, eg: escape, defeat evil overlords, etc. This main objective compels you to build/explore/fight. But how you ultimately succeed, has not been pre-ordained by the dev’s, you use your own wits and the sandbox world to succeed.
