Pay to play, if you don't purchase every hour, you're not playing. Everything takes hours to replenish & upgrade. All you can do is gather resources for hours until you can play again. In the meantime you're bored. To many bugs as well, if you purchase something you don't receive, well that's to bad, you have to be psychic and take a picture of what went wrong before it does so they can supposedly help you. Definitely not worth it. Boring & expensive.
