Never play this series before, is it a game with warfare to expand the empire?

[Dr. Dan]

just like HOI series but with different gameplay and setting? ( and ofcoz I know different period of history)
Thank you!

Same overarching concept of conquest, but many different peculiarities. You could go a peaceful game in theory, but that'd be rather boring. When compared to EU3, you still don't need to do much with merchants or colonists - slight increase in management.

It really is learning something completely new.

The new "claim province" action coupled with no infamy mechanic makes military conquest much more of a breeze... Royal marriages and voluntary vassalization is another way to conquer though.
