I recently purchased the Crusader Kings pack off of Amazon. It includes the game and all of the dlc packs. I was wondering if it would be better to play just the base game first, or should I go ahead and install all of the dlc and play it like that for the first time.

Also, is it worth it to play the first Crusader Kings, or should I just skip straight to two?

playing it without the DLC just gives you less options, so enable all dat shit.

also, the original CK is not worth playing if you have CK2; it's alright but CK2 is in another league.

I'd turn off Sunset Invasion. The game is difficult enough to get into without Aztecs going on a warpath.

You might get overwhelmed with all of it on.
