I think Paradox is smart to be making the political system and economic system better instead of focusing on WW1. The game already has a really good foundation in both these areas, and right now they both feel a little bland after multiple playings. By developing more flavor and mechanics in these areas I believe the game is going to be amazing. I also think it's smart to focus on these areas first. By hammering out the mechanics it will better help set the stage for an expansion that focuses on a great war. By figuring out the various Political mechanics now, they can better then develop a great war expansion. I think if they worked on the great war now, and then tried to make politics and economics better later, it would be a bit like working backwards.
So thanks Paradox for focusing on the Politics and Economics with this first expansion. IT's primarily what I bought the game for.
