You don't need this DLC to play game at all. It doesn't has any feature that playing without makes game unplayable, but it has a lot of small ones that can make your games more in depth and allows for more freedom in your game. The big features of this game as of more depth to Middle East and army professionalism don't make this dlc worthy in itself. What makes it worthy however is making small changes like promoting advisors, exploiting development or allowing to use missionaries in your vassal provinces. From big features exploting professionalism serves good as additional manpower pool and it buffs Mameluks, so Ottomans don't have so easy start for their blobbing

While not my cup of tea, Crusader Kings does a good job at what it sets out to do. From being very historically accurate with rulers and events, the wacky unexpected events to set it apart. Not for the faint of heart when it comes to strategy games; will test your intellect. Recommended for those who specifically enjoy "grand" strategy games over large maps and those who are willing to spend 100 hours in just one game.

This DLC for Crusader Kings: II does not offer much, thankfully it's price tag reflects that, but it can be very important to fanboys of the Holy Roman Empire and subsequently Byzantium. Recommended for those crusaders looking to reunite the Roman Holy Land.

This clan adds a very unique playstyle to the game, with the ability to rapidly expand by using civilians to clear out wolves and even drauger (in enough numbers) before building any military units. The reliance on Thralls (mainly for sacrifice) means you need to keep upping your gold production to keep buying more unless you can capture them in fighting. Overall a really unique clan and a great addition to the game at a good cost!
