It's been a great time killer, which is a big plus for me because I very rarely buy new games. If your worried about having to be way into building like some Minecraft players don't be, it has plenty of goals to go after without that in mind. If you do enjoy building, however, it's still great. Early on it started out pretty small but as time went on it added a lot of content onto the base game. At this point, it's a great purchase, though the last update is coming soon.
You want look into gameplay videos online first if your interested. Get a sense of what the game is like.
