In regards to setting and discussion of story, we’re generally applying Xianxia to more fantastical Chinese fantasy and Wuxia to more grounded (though still probably fantastical) martial arts fantasy. There’s a good explainer of this in r/fantasy on reddit. For example, Cultivation stories about quests to become immortal and interacting with deities are a Xianxia subgenre. But since we’re applying tags to games to help people find them, sometimes we’ll have both tags on a game that could appeal to fans of both subgenres. Generally this just means more liberally applying the Wuxia tag to Xianxia setting games that also include martial arts.
