Anyone who'd like to have actual answers to this question should go check out the Asians Represent YouTube channel and watch their series where they go page by page through OA and comment on the stereotypes they find in there and what they think about them.
You may or may not agree with their takes after you hear them, but informing yourself about what actual people who have actual issues with the text think are problems is the first step towards, you know, thinking about the issue from a perspective that isn't your own.
Obviously, it is rather difficult to tell people to watch a 26 hour series of youtube videos in order to comment; they'd save a lot of time looking at previous threads here to see the main flashpoints of contention.
I am loathe to re-enter this conversation given that this was thoroughly hashed out before. However, I think that it is important to note several of the overarching criticisms of OA used in the series were .... shall we say exceptionally similar to the 2016 article in Analog Game Studios. And as
@Alzrius and others pointed out
, many of the specific criticisms in that article that were later used in the Asians Represent series
were pointed out to be incorrect at that time (in 2016). Flagrantly so.
The most famous example is, of course, comeliness. This was not some attempt to "exoticize" the other or make Asian men seem effeminate (??), instead it was a new statistic that was driven by Gygax and previously included in Unearthed Arcana to be applicable to all D&D games. Another is the inclusion on "NWPs," which, far from being some type of "othering" mechanic, was an introduction to a use that Zeb Cook would expand upon in 2e.
More importantly, many of the criticisms seem bizarre, and under the "heads I win, tails you lose," category. Almost everything is seen as being negative because it either portrays Asian culture as barbaric, or too mannered & civilized; these are, of course, incompatible criticisms. Now, that doesn't mean that you can't have conflicting analyses (offensive stereotypes don't have to be logically consistent), but the "close reading" of the text is overly inclusive in terms of finding things that are a normal part of "D&D" and labeling them offensive.
All that said, if someone wants to take offense at something, they can. The term "oriental" is widely considered offensive now. While a specific time period is hard to pin down, usually the 90s is seen as when that word became a serious issue - of course, you can always go back to Said in 1978, and prior examples, but there wasn't any widespread concept.
I also think that both the front cover and, definitely, the back cover (with it's exoticizing language) is certainly problematic.
The most important issues, IMO, when it comes to how offensive you believe the book to be really come down to a few things-
a. The swirling of distinct Asian cultures into a pan-Asian, but mostly Japan with a little bit of China and a very little bit of Korea, thrown in.
b. The "gamifying" of aspects of Asian culture in the same manner that had been used elsewhere- such as
Deities & Demigods (giving real-world religions and gods stats and hit points) or the base AD&D books.
c. The mix of real-world history, from different periods, with a heavy influence of media portrayals - a book that takes inspiration from both actual history as well as genre works that feature ninjas, samurai, and kung fu warriors.
d. Those issues that are specific to being Asian-American* in the West. I know that at the time and going forward, the book was very popular with many Asian-Americans as it provided representation that was previously missing from the game; on the other hand, I also knew people who were disappointed that the book was more about specific countries and genre conventions, and did not feature examples from the very rich tapestry of other countries, such as Thailand, or the Philippines, or any number of other cultures (which I am using the shorthand of the country to refer to) that are not present in the book.
It's an interesting question; I know that given the paucity of material at that time, and the introduction of OA, caused a generation of people (including me) to get more involved in the actual history of Asia, and to start consuming more media that was made there. But for OA, I might not have started seeking out the productions from Hong Kong and Japan that became a staple of my viewing. I probably would not have traveled to Asia in the 90s. My life would have been a lot poorer, due to lack of exposure.
None of this is said to excuse anyone's pain; obviously, my personal experiences and travel doesn't outweigh the pain it might have caused. But I think that tolerance and understanding often come first from exposure and knowledge, and while OA is not up to the standards of today, I would assert that given the standards of that time it certainly did more good than harm.
IMO, YMMV, etc.
