I like the tree house. I know u can't get the item without buying gems (which I'm disappointed to hear that the gem sales are rare CS gives them to me all the time and I love them ) but u don't have to get that item. I'm not much into decorations so I use the darts and get other stuff I need like I got a fish sandwich already and a ring. I did buy extra darts once and got a dog which was still cheaper than purchase it in the market. So again just my opinion. Enjoy
