I have a bunch of the DLCs and "only" played less than 200hrs.

The game is fantastic. It's the real roleplaying vibe, the idea of creating the history of a dynasty and dealing with the events is great.

The mechanics are DAUNTING to the beginner, but to me, figuring them out and reading about the game and its complexities are a huge part of the fun. It will get frustrating though, as you fail straight away, or after going Game Over because of a stupid decision that throws your 12h playthrough straight to the trash.
It's a game for people who love the high-stakes, for people who love the complicated mechanics and depth, and especially for people who love dealing with cause and consequence.

While not all the DLCs are great, a lot of them do well in expanding the game's capabilities.

Oh, and this game generates the funniest things ever to be found in videogames.
