The game has its improvements compare to the past.
the levels of different stages of improvements of buildings are good. However the money system can be better. It takes a long time to be good at earning good money and more options of good and easy money can be earned so to support better war battle efforts. Of course is the game is plainly building and economy then it is ok. However, some features can be added. Because if the enemy start the war first and break your supplies, you are doomed. no way to survive at least for me. Hence some features of generating money should be there to make it more interesting during a war. the war starts and no supplies means riots and you are lost. you do not even have money to build an army to defend. cos money is running out fast.
The game is still great but some of these features can be looked into.
