On the other hand, it also largely sticks to the formula established by its predecessors. It's an excellent grand strategy game, just like all of Paradox's titles, but its clear the developers were playing it safe.
If you've played Crusader Kings II before (or any other Paradox title for that matter), feel free to jump into EUIV. It might seem overwhelming at first, but the two games are similar enough in style (if not in core mechanics) that you'll quickly gain your bearings.
For those looking to enter the grand strategy realm, however, I'll still have to recommend playing Crusader Kings II first. Because of its focus on personalities instead of countries, it remains an easier avenue for traditional players to get a hold on the genre before trying their hand at something more complicated.
And who knows? Maybe you'll get hooked.
