Yes, most of us know that but the Simplified Chinese seems to be "unused". If that's the case, then I have no clue what the "Chinese" depot is. Anyway, back on topic. Bison could literally mean anything. When I first heard about BNW, I immediately thought to myself, the New World! Apparently, there were only 2 civs that were from the New World. So Bison could be a clue to a native plains tribe, but Firaxis might stump us and add a completely different civilization that has nothing to do with bisons, or a scenario about the natives of America before Columbus (or after).
