Takes WAY too long to do really anything. Just when you get interested, you realize how little you can do now, and how long everything actually takes. Example, you can only build 1 thing at a time because you only have 1 builder. You can buy more with cash, but without actually using money, you're stuck with 1 incredibly slow builder and EVERYTHING needs to be built up. Even the vault needs to be built up because it can only hold a small amount. Too slow!
