Best Medieval Grand Strategy Game

Crusader Kings II

PC

Paradox Interactive

Crusader Kings II is a wonderfully robust grand strategy title from Paradox Interactive that puts you in the shoes of a medieval family, who may or may not be a preeminent power during the period. You can play anyone from a lowly count to a mighty emperor, managing your dominion, choosing who to marry your children off to, how you  will interact with your underlings and who you will go to war with, or who you will just assassinate.

The game is riddled with not only military glory, but political intrigue, interesting and unique procedurally generated characters, and cloak and dagger diplomacy. Paradox has so far supported this title very well with multiple DLC packs, and hopefully more content to come. (JUST SHUT UP AND TAKE MY MONEY)
