5 stars: Simple. Yet enough depth to keep you engaged. Plenty rewarding. Constantly expanding in some way. Plenty new features from units, to upgrades, to structures, etc. that are often being introduced to keep things fresh as you move through the game. But, not at too rapid of a rate.

4 stars: Incredible game with unique features. Although there are some minor bugs and expensive in app purchases. For older devices you may experience lag or even not run on your device. In addition, there are no ads unless you want them. Overall, it's not pay to win and you can progress without spending a cent.
3 stars: It's a good game and all there are a couple of downsides I have to say, there is no recall of all buildings, you have to individually pull all of them back, no masd upgrade, and it doesn't really sort out the toughest from the weakest, if you could improve that aspect of the game it would get 5 stars from me. Love the game though
