Meh. I just want cultural distinction, not historical distinction.
The section you cut from before that in the quote, though, is perhaps the key part to be replying to: is this a rule you'd apply as equally to European-based games? Or is it impossible to really judge it becuase the things we do with our baseline European culture seem so different to when we do them to other cultures?
What's perhaps an important note for my sample data given is that it's for an oriental world that exists alongside a European one: i.e. it's a foreign land to be travelled to, not a base campaign world. I'd probably want something far more traditional if people said "I want to play an oriental campaign", since odds are people specifically mean "I want ninja, kung fu and serpentine dragons". But when it's sitting alongside other D&D material, I don't see any reason to treat Asia different to any of D&Ds other sources.
