This is actually in the game, already
you simply run around telling people you are an indian, and refer to others as pale-face or white-man
This game is what you make of it. You are a part of any faction you chose to create. Currently I am a part of the Carealot faction. The difference between us and other players is that we care. A lot. I am obviously grumpy bear. Don't be fooled by my gruff exterior, I actually care. A lot.
