This game gives out as much as you want to put into it. I've dumped 150 hours into one world, i've built mountain castles, massive trading ports, highways for my villages and outposts and still have a boss to fight.

You can have a simple life and work out of a small fort or you can let your creativity flow and build whole living worlds for you and your friends.

If you just want to "win" as soon as possible you could maybe do all the bosses within 40 hrs, assuming you're meta about your play style. If you are like me and like to explore and built your world out then you will get hundreds of hours out of this title.
