มึนกับ DLC เหมือนผมเลย ซื้อเกมหลักมาไว้แล้วไม่รู้จะซื้อ DLC ตัวไหน สรุปคือดองยาว - -"
แต่เห็นเว็บนี้มีรีวิว DLC แต่ละตัวไว้นะ
http://www.strategygamer.com/articles/crusader-kings-2-dlc-buying-guide/
สุดท้ายแล้วสรุป DLC ที่ทุกคนควรมีคือ

Essential Expansions for Everyone:
    The Old Gods
    Legacy of Rome (Specifically for the Retinues feature)
    Way of Life
    Conclave
    The Reaper’s Due


ส่วนเรื่อง GOT นี่ เห็นใน wiki บอกว่า Game of Thrones Mod ไม่ต้องใช้ DLC นะ

"Q: What DLC does the mod need/use?"
A: The mod should run fine no matter which DLC is enabled/disabled.

แต่ถ้ามี DLC จะมีอะไรๆเพิ่มขึ้นใน mod ตามนี้:

    The Sword of Islam: Adds only the ability for the player to have multiple wives as a character of the Valyrian religion.
    Legacy of Rome: Adds castration and blinding capability as well as a couple of flavour events. It does NOT add retinues.
    The Republic: Allows the Merchant Republic realms to be played, namely the Free Cities, Meereen, Yunkai, Astapor and the Guilds of Qarth. These realms will still be active even without the DLC.
    The Old Gods: Enables the concubine system for Drowned God and Harpy followers (Pre-DLC system will be used if not enabled). Also adds much flavour, including berserkers, adventurers, new rebels and runestones. Raiding is available for drowned god, wildlings and pirates even without this DLC.

    Charlemagne: Adds the chronicle, custom kingdoms (existing titular kingdoms are still available without DLC) and a 'hero knight' flavour event
    Way of life: Enables the focus system, allowing a ruler to pick any of the foci available with all associated events decisions. Seduction focus replaces 'visit chambers' interaction when DLC is enabled
