Crusader Kings III: Fate of Iberia Review (Churchill)
Sadly, this is not a great expansion. The idea behind it is great, but execution is weak. Playtesting, and especially feedback and reacting to any testing is almost non-existent.
As an expansion that is exclusively related to one quite small (geographically speaking) area of the map, I would expect it to make some fairly major changes, especially at that price point. If you are going to raise the price and cite 'quality' as your primary reason, then you'd better be ready to prove it. None of the recent CK3 expansions have shown me a particular improvement in quality or quantity.
The new events in Fate of Iberia are ok, but noone is going to buy they are of somehow better quality than events that were present in vanilla.
The Struggle mechanic is the big tentpole attraction of this mechanic, and to be frank, it severely disappoints. The amount of influence the player as a single ruler can exert on the progression and direction of the struggle from phase to phase is minimal. It is almost entirely RNG directed by how the AI chooses to act. It is entirely possible for the struggle to end in just three phases, with an AI muslim ruler (because they start with the land early on, and therefore the most events which means the most points) deciding that noone should ever form the Empire of Hispania, and everyone else just.... goes along with it apparently. Even though said ruler has barely 1/3 of Hispania. The lack of control for an individual ruler may be historically accurate, but it is not good gameplay, and this along with issues such as being able to control all of Hispania but stuck with the Struggle still ongoing and unable to form Hispania just demonstrates a lack of QC, and lack of attention to detail and a lack of proper playtesting. Which pretty much blows your argument of 'quality' justifying higher prices out of the water.
Outside of the Struggle, there is very little going on here, to the extent that I noticed zero difference with this DLC when not playing in the Iberian Peninsular.
If you had said cost of living, energy prices etc are making it more expensive to make games, and in order to maintain your business model, you had to raise prices, then while it might not be a popular decision, it would at least have been an understandable, and more importantly HONEST one.
