このゲームは歴史シミュではありますが、最たる特徴は国ではなく王朝に焦点をあてている点です。

Methodology and sources
Data
Steam user reviews, retrieved with Steam's public review listing between 2020-09-02 and 2026-10-23: 335 written in Japanese. Steam's own all-time totals for Crusader Kings III were read on 2026-10-30.
How the reviews were classified
Every review was read by a language model, which rated how positive it is, how much concrete detail it gives, and which of 15 fixed topics it talks about. The counts and percentages in this article were then computed from those labels in ordinary code, not by the model. Automatic classification makes mistakes, so single percentages should be read as approximate. Reviews of fewer than 15 characters were not sent to the model; they count as positive or negative from the reviewer's own recommendation and carry no topic.
Limits
People who write a Steam review in Japanese are not a representative sample of everyone who plays in Japan, and the language of a review does not establish where its author lives. Steam's default filter for off-topic review activity was left on, so periods Steam marked as review bombing are excluded from the counts in this article. Reviews that arrived after the retrieval date are not included.
