I checked out the 7 page spread in Commanda Quarterly, but didn't notice anything on local language besides a vague reference in the Chinatown description.
In 2071 what are the local languages spoken? First natives languges. Does Hopi fall under the Uto-Aztecan umbrella? Is Zuni considered to still be alive? What about Lakhota-Dakota in the Sioux sector?
What about Romance (Spanish)? Or Chinese? Are they intended to be handled by specific dialect/sub-language, and if so which dialects are the two Triads speaking?
Or is this all pretty much up to the specific GMs to dictate with no guidelines other than the official material doesn't really get into languages. (I haven't read any modules yet for fear of spoiling).
