You should try it with the Pop demand mod, and maybe get the expansion. It takes the game to a whole new level.
I do have A House Divided with it. Don't have the Pop Demand Mod though I've heard its great (also New Nations mod) but I've never played any mods before and have never looked into how to do them. Also, I play on a Mac so I always assume it either won't be compatible or will be a pain in the ass.
I've had lots of fun with CK2, it is my favorite of the paradox games. I recently bought Victoria 2, but I feel like I need an instructor to play it. I imagine it would be great, if I knew what I was doing.
If you think it's bad with Vicky2, you should try Hearts of Iron 3...
