There are many hundreds of tags in the game and up to now focus has been on making sure none use the plain base idea set. We are almost there but ideas take time to write and research so it's all a matter of priorities.
If you suggest new ideas for Native American tags that are well researched and written they'll have a good chance to get added to the game
