Something else I thought about: If they do a game based on a historical conflict like the Rachni Wars, then how will they incorporate choice into it? There's a canon ending to those conflicts. It's not like you can change it where NewShepard has the choice of forcing the rachni into extinction or letting them go; it's already been decided.
