The Early Access version will have quite some playtime but it is hard to tell a certain number of hours as it is very much like a sandbox. There is a way you can actually “win” and finish the game but this includes a very hard fight and you have to be well prepared. We also have three difficulty levels you can choose from when starting a new campaign and the hard setting will take much more time than the easy one.
