Crusader Kings II is more than three years old and new expansions are still releasing for it. The latest, Horse Lords, takes you to the Eurasian Steppes to bring the nomadic Mongolian menace to the people, Genghis Khan style, and it's out today.
CKII is a crazy game for crazy people. A grand strategy game with a game board that looks like Risk Nightmare Mode, it's tailor-made for lunatics who enjoy the political intrigue of medieval era court life. It has all the betrayal, manoeuvring and incest you could want wrapped in a learning curve so steep it inverts over and marries into it's own daughter learning curve.
For the first score or so hours in the game, you'll spend the majority of it just trying to not be assassinated by one of your vassals (who is also your son/nephew). Eventually you'll get a handle on the game and you do your best to perpetuate a long and prosperous lineage as the new Pope or something. That's CKII at its finest.
Until now, it seems. Horse Lords includes Nomadic rule, Clan focused politicking, an increased map size (to get the people of the Steppes in on the action) and the option to name your own horse. You only get to choose from a list of names though, and none of them are Cinnamon. Nobody would mess with a horde of Mongols lead by a man riding a horse called Cinnamon, because you know that guy has already fought every battle there is to fight.
The DLC is available on Steam right now for $5.99, but it requires the base game to play. And you'll probably want a few of the other nine expansion packs as well. Who's up for some horsing around? What are the must-have expansion packs?
