Europa Universalis IV Explored
I detailed a number of things on my Paradox EUIV Wiki Page in the fall of 2014, check it out.
It's a great game; I've sunk tons of time into its many versions over the year. It gets kind of hinked up in details but then, how can you not, when a game goes this deep.
Paradox gets an infinite A+ for continuing to support their games and improving them over time.
But the downside is that an update shortly after I posted the above info, left all my Papal Cardinal work in the dust.
So I moved on.
C'est la vie.
