The game worths 18.99€, even with all the issues which were raised by other players. The development team did a great job with the graphics, mechanics, ideas and so on. Also the development team seems very listening to the players, since there was a day 1 patch and more to follow to fix all the issues and implement new features.
Also I read on forums, there will be more content added, mission, maps, campaigns, units, buildings, etc ... for free or as DLC, so this game has a solid foundation on which to grow more.
As everyone said already the game is in Caesar, Zeus, Pharoh style, but the more important is that it's an up to date version of those games, with new ideas and features and more than that ... I like the developers passion since they are struggling to fix all the issues and to please all the players ...

Update: 1 year and 6 months after the initial review and the updates, improvementes and new features are still coming for this game .....
