Its just too difficult and you don't progress fast enough. Roadblock after roadblock after roadblock. The game becomes way to tedious. Some of the events are just plain boring. You progress at a snails pace while the game constantly tries to get you to spend money on it. I watched all my friends quit the game over boredom. I'm pretty much done with this game. I don't advise people to start playing this game. It's just not rewarding enough or fun once you hit a certain point.
