I think there should be a tutorial world that teaches the basic survival skills - gather essential materials, clay crafting, cooking, quarrying, etc. and ends at smelting copper. Make a small world (maybe a couple thousand block radius) that has everything needed to get to copper. Make the game a bit easier, buff player a bit (higher HP, lower hunger) lower wolf aggression some. Provide pop up bubbles that give direction about what to do, i.e. when player comes near clay bubble informs player that they will need clay to form items, like storage vessels. Overall it would be the exact same world to help people conquer the huge learning curve.
