Except that you don't have to go back much more than a century (and in some cases - rural France, the rural South, Latin America, etc - not even that) for the cultural distinction you mention here to be pretty much unnoticable. You aren't picking up on a cultural distinction that is Western vs. Eastern, as much as it is post-industrial vs. pre-industrial. Nothing about the pre-industrial West anywhere in the West would have been different than what you describe. In fact, in most societies prior to the 20th century, it would be unusual for children to not live either in their Parents house or as neighbors on the same property or for an unwed woman to live anywhere but with her parents.
I wouldn't agree with this. The distinction between Japanese and American/European videogame RPGs is far from a reflection of large historical traditions. If anything, it is merely a difference in style between two geographically separate groups, much like how every other artistic style or artistic movement tends to be specific to a geographic area.There's also a significant difference in the storytelling traditions between Western and Eastern cultures. Just take a look at the difference between American (and other western) computer RPGs and Japanese ones.
In terms of history, the differences between the different regions in the stories people tell and the way they tell them tend to be far more subtle and minor, and generalizing it into a difference between "Western" storytelling traditions and "Eastern" storytelling traditions would be a grave mistake. I mean, even within just Japan there are a number of different conflicting traditions for storytelling, performance, and literature, and trying to lump just those together is a disservice. This isn't even getting into complexities like the fact that ancient Greek theater resembles various eastern forms of theater more than modern theater, yet Aristotle's writings about the theater of his time was a major influence upon many later forms of theater in the western world...
I suppose that is fair, but at the same time I think that the American vs. Japanese videogame/computer RPG distinction is proof that such influences are not as significant as you might think. After all, both American and Japanese videogame RPGs share the same root: Dungeons and Dragons. The most important and influential games in the early days of American videogame RPGs were all licensed D&D products set in familiar settings like the Forgotten Realms, and, while less official, the influence of D&D on early Japanese videogame RPGs is just as clear (among other things, the original Final Fantasy contains Bahamut, Tiamat, Elves, Dwarves, Drow, a Marilith, Mind Flayers, mages split into Black, White, and Red colors like in Dragonlance, and typically assumes that you have a four-man team consisting of a Fighter, a Thief, a Black Mage/Wizard, and a White Mage/Cleric). The main difference started with differing ideas on how to transform the D&D experience into a game, and diverge from there, mostly as a product of the preferences and goals of individual game designers.Sorry, I didn't mean to imply that there were ONLY two traditions of storytelling, but rather that, were D&D invented in a different cultural context, it seems likely that the storytelling tradition it would be born into/from would be different as well. American vs. Japanese CRPGs was meant just as a specific instance of that.
Considering the stereotypes and historical inaccuracies in DnD regarding the assumed Western Middle Ages setting? I'd say about the same as we have now.
The West basically abandoned class, or made it anachronistic, long before the East, because of religious, economic, and political reasons. (Instead many in the West were far longer fixed upon the idea of race, rather than class, in a way making race a sort of "de facto class" in many cases.)
I also say it would look a lot like real D&D. It is not like D&D is remotely close to historical accuracy. Actually, I think the makers of various Oriental Adventures products were probably more interested in historical accuracy than the creators of core D&D were, and probably more so than the hypothetical Asian creators of D&D would be.
All of my experience with Japanese anime, manga, and videogames seems to back up that theory, at least.
Umm, that doesn't sound much like England. Here class still beats race in most social interactions, IME.
Fair enough. But this still shapes the fantasy worlds the respective cultures would create. Though there does seem to be a religious devotion to parents in Thailand, that is nothing like we had in west that I can think of.
I also think that while parents in the west traditionally have had the final say on matters, she wouldn't even think of objecting to anything her parents suggest.
They often compare their parents to angels.
Also, is it fair to say it is pre-industrial vs. post industrial. I mean my wife comes from Bangkok, a fairly modern city. Not like she is herding animals in the country side or anything. I have found this same level of respect for parents with Japanese and Korean people I have met through my wife, and both those countries are highly modern.
