Bumping this thread just for discussion about Paradox games in general. What I find really interesting about them is that each one plays so differently. I can't decide if this is a good thing because it certainly shows a lot of effort, or a bad thing because every game has a new learning
cliff. Crusader Kings II is completely different from Hearts of Iron III which is massively different from Victoria II which is different from EUIV, etc. While it's nice to have different ones to go to when I'm in a certain mood (Crusader Kings II for a story, EU IV for Risk, etc.), this is probably offputting to new people and hurts the new player experience.
It's a similar thing to Civilization, where they feel the need to completely redesign the game each time, which means most people just find the one they like and never move on (it was 3 for me).
