Well, I am definitely troubled. I only wish more RPG products were this troubling.

Yoon-Suin initially stands out as a creative and ambitious work, with its psychedelic art and evocative writing. However, as you dive deeper, and particularly into the career and attitude of its author, David McGrogan, you discover a troubling setting riddled with orientalist tropes.

GMs and players interested in exploring a setting with "oriental furniture" might find Yoon-Suin appealing, but they should approach it with a critical lens. The OSR community thrives on creativity, collaboration, and openness—qualities that McGrogan doesn't seem to posses.

McGrogan once described Yoon-Suin as "Fantasy Tibet by somebody who has never been to Tibet," a candid acknowledgment that has since been replaced by a defensive blog post. He goes on to gaslight anyone criticizing his troubling inference to real world cultures by saying, "If you are worried that is my intention, don't. If you are worried others will draw that inference, that's their problem." The orientalism in Yoon-Suin might have been forgivable (maybe except for the opium and tea bit) had McGrogan shown a willingness to learn from critique and engage in meaningful collaboration.

I don't recommend Yoon-Suin, but if you are going to play Yoon-Suin anyway, please do the due diligence of being critical and engaging in conversation. The OSR community is better because of it.
