Psychologically the worst game! It's highly addictive and laggy. Lots of money spenders and if you're to keep up with them, you've to spend too. Developers keep adding new features, generals etc. but will not spend time on removing the lag. Customer service is like chatbot. They've a 30-40 set of answers and depending on your query, you'll get one of the answers. But if one goes on and on with the complaining, they will give some resources as compensation to numb you.
