New trailer showing a lot more stuff and some they have already shown too. Looks like there will be boss battles and also settlements. I got about 10 hours in the demo so far, no more quests to do but I can still sail around and sink ships or build my own little settlement further. Building in this game is smooth as hell btw, when placing foundations, walls or roofs you can just keep holding the mouse button down and drag it to build multiple of what you want as long as you have the materials, and any resources inside chests within your landclaim is automatically used.
