Good DLC, worth getting when on sale. Everything is expanded from native.

There are few flaws, expensive troops that you need to grind so long to get can die in few hits, annoying bugs, and hardcore campain.

Worth picking this up on sale, you are locked out of a few features without it.

To many, Conclave is an under appreciated DLC, which makes the game more difficult by increasing the power of a ruler's council. This, however, is incorrect, as the council's power can be pretty easily managed through shrewd planning and placing the most powerful vassals on the council, regardless of their skill. The improved education system is also a huge improvement on the vanilla education system. The improvement on laws also streamlines the game, making management easier, and unlocks new options for realm management, along with the new law voting system, which requires only a majority of the council to approve for the law (5-10 characters), instead of requiring a majority of all of the vassals of the realm to approve it. Playing as a vassal is also improved with this DLC, as it gives more flexibility to those who sit on their ruler's council.

As with all Paradox DLCs, consider purchasing this on sale.

I have mixed feelings on the contents of this DLC. On one hand, it adds a whole lot of customization options to industrial zones, but at the same time, growing the districts becomes a manual task instead of just zoning out an area. You have to balance production levels lest your factories run dry of materials, and the UI is a bit cumbersome for that. On the other side, the new zones are a great source of revenue, and it adds a lot of tools to visually and thematically customize your city, if you're into that sort of role playing.

Despite some complaints that this DLC makes the game harder, it makes a good effort at better representing the effect of disease in the Middle Ages. Without this DLC, the "Ill" trait is not even close of an accurate representation to how debilitating illness would be to a ruler. While the amount of diseases are limited, and should be expanded to include more disease categories, the epidemic system is strikingly accurate. The prosperity mechanic is also a good addition to the game.

As always, while this DLC is good, consider buying it on sale.

Very deep strategy game with a great campaign. Mechs are very customizable. I love the long range abilities of some of the mechs. Highly recommended!

This DLC is essential to any CKII player. The addition of permanent armies, Retinues, makes army building much more fun, and the addition of extra flavor and events for the Byzantine Empire and Orthodox religion adds some extra fun stuff. The DLC is also extremely cheap (5 USD), and can be purchased on a sale for less than the price of a cup of coffee.

Overall, this DLC is essential, and I would recommend every CKII player who does not have it to consider investing the price of a cup of coffee into their game to greatly improve their experience.
