Play Crusader Kings II
Be me, some vassal of the Byzantine empire in what would be known as southern italy in the modern age
Don't have to worry about an entire realm, ammass my wealth in peace, plot people's death for fun
Some other guy creates a "we want indipendence" faction and I join it for fun too
Somehow emperor Kostantinos decides he doesn't have time for this shit and grants us indipendence. All right then
"Pick an Ambition: Become King of Sicily", sounds cool
Have to suck the pope's clean every single day to get those damn claims, years pass but little by little southern italy gets recolored to my color
Finally, Sicily is mine, the kingdom is born, ambition completed
In the meanwhile emperor Kostantinos died and I didn't even notice, entire Byzantine Empire is filled with revolts, "rebel states" every 3 counties
The entire "history" has already flown out of the window, meanwhile notice new option in the intrigue menu: study the classics. Let's pick the ones about the ancient greek religion
"The stories about these old gods and their intrigue is much closer to the chaotic state of the world we live in. Are we really sure the one true God is the real deal?" thinks my character
I'm indipendent so nothing stops me from recreating the Hellenic faith. Convert my spouse, "convert" my vassals into different vassals that follow this new belief
The Papal States are so close, and they're so small, while my kingdom gets more greek each passing year. Time to take all those stupid claims and shove them into the Pope's throat
Hmm, yeah I see now why the Paradox Grand Strategy games have their fans
