The best of the Paradox grand strategies in its ability to develop a proper economy and show the progressing warfare of the era pretty well with techs, even if the game does become far too defense focused making it hard to push late game. The depth this game has is quite amazing but it's not particularly hard to understand on a surface level compared to the other grand strategies which require a bit longer to pick up. The main drawback of this game is the AI is pretty bad in this game, in war and nation building but it seems like that's the norm for these type of wider strategy games these days.
