Ok game if you like the genre. Are things that could be done better, which is reflected in that it will release an expansion, but only as a download.
Sad it is that Paradox joins what is becoming more and more popular among game makers nowadays, ie to release patches as "expansion" and charge you for it. Besides, it has things in expansion that should have been included in the original game, sad.
New players should keep in mind that it takes time to understand how the game works, but keep you so rewarding it off in the end.
