Great game. Great gameplay, but variety when it comes to National Focuses is a bit low (Many nations use generic focus trees). Paradox makes great games, but it takes time to get there. Overall, I recommend it.

Edit: As a long time has passed and multiple dlc's as well as many well done mods have been released, I would say that their is quite a large variety that goes from Science-Fiction to alt-history that reshapes reality in game. I would, without a doubt, recommend this game. It does have a learning curve that takes time to get used to but if you labor on and invest some time, the game really opens up.

Edit 2: Still a great game with tons of content!

Edit 3: Still a fun time sink
