I play CK2, how similar are they?
Similar in spirit and that they come from the same people, however the core gameplay is different (though armies and fighting is basically the same except that its adds naval battles). However, while CK2's focus is playing a specific character and all of the politics involved on that level, in EU3 its more of the traditional "I'm playing a country" strategy game mindset.
The scope is a lot of fun though and the huge time period gives way to a LOT of re-playability and different things to do. Colonize, focus on a trade empire, be a continental military power in Europe, etc. etc.
Although, I have to say that I recently acquired Victoria 2 and a have had a ton of fun with it. It's pretty amazing and so the way the time period is captured is very impressive.
