Nice response - and just to be clear, I am aware of--and largely agree with the gist of this perspective, though I think it veers a bit away from what I was talking about. To address your points...
1. If someone was making a game that was very deeply inspired by the folk lore, culture, and natural environment of, say, Scandinavia, then I do think the project would benefit from people who were more closely connected to the culture. Many Free League games, for example, have a sensibility that would be hard for a company like wotc to capture
Yes, agreed - and this relates to what I was saying. Further, "Scandinavia" pinpoints a specific enough culture, or set of closely related cultures, that consultation by representative people makes a lot of sense. But "European" is far more diverse, and includes hundreds of ethnic and cultural groups, especially if you extend back to ancient times.
2. There are other geographies other than strictly national ones. The United States was obviously an English settler colony and dominant American culture is inundated with European cultural references. We read english literature in school, learn about European history, learn European languages (often poorly, but still). Politically, America is part of the "global north," and culturally associates itself with the geography of "the West."
Yes, understood. Still, "European cultural references" is quite different--not to mention generalized and Americanized--from understanding of a specific European culture, especially a pre-modern one. Or to put it bluntly, being American doesn't qualify one to write knowledgeably about Celtic history or ancient Greece.
3. Historically, "the West," including both Europe and the United States, has viewed the economies, cultures, and peoples of the rest of the world through an extractive lens--taking land, enslaving populations, but also taking the stories and culture of people from around the world. Sometimes these cultures (including languages, mythologies, histories) have been outright destroyed, sometimes they have been put in museums in the west to be viewed as artifacts, and sometimes these cultures have been turned into very reductive stereotypes. That last bit is known as exoticisation and orientalism.
Again, understood. But I'm still not sure how this makes a 21st century American inherently qualified to write about any and all European cultures, even if they share an overall similar geo-political landscape and context. Meaning, regardless of what your ethnicity is, or what you're writing about, it is still a good idea to know what you're writing about.
I would also argue that the lack of orientalism or exoticism with regards to, say, depictions of fantasy European cultures, doesn't mean they aren't generalized or even outright butchered by American (or other) authors.
4. So when people in "the West" create something, they should be aware of the above history and the way that it allows for and impacts what they do, both for the sake of producing a better product and for having an ethical relation to their creators and audiences. Game companies should consider whether they have minorities on their staff, not just as writers but in all areas. They should consider hiring writers from the global south who both have more knowledge of their cultures (and access to knowledge through their knowledge of language) and who face structural obstacles to making a living as a game designer. And they should consider how audiences--all audiences--might receive their product.
All of which I basically agree with - although I think it veers away from the view I was presenting, which is not at all antithetical to what you're talking about, or the basics of colonial history that you describe.
Or to put it another way, I think we're talking about two (or three) separate things:
One, whether or not an individual (Western) designer understands colonial history; and
Two, whether or not a company has diverse hiring practices (and I would add, ideological diversity), and...
Three, who is the right person for the job, when writing a specific book.
I don't think the three are the same, that they need to be addressed separately. And furthermore, that the first two don't necessarily "solve" the third.
