There is a lot of depth to this game. Or at least it seems. I've always been looking for a game that balances RTS combat with resource management/city building. This is a perfect fit. Seems to lack nothing. My only complaint would be that the UI is a bit complex but honestly it's not that bad. Has a lot of variety and your city develops if you manage it well. It's very visually appealing too, I prefer the 2D isomorphic visuals over 3D visuals in games like this, I wish they still used this visual style. I highly recommend this game.
