Fun but takes a while to learn to run the app but once you learn it it gets better, then they change it. There is a huge unfair advantage to paying customers who can grow bigger and faster because they purchase. It's NOT a kids game.

I believe the population of that realm would be huge!. You cannot take time to enjoy growth.
