The door has seemingly shut when they start adding Vampires etc. to the game. Rather than giving us Merchant companies or something like that to the game they decide to go the route which doesn't even belong in such a game as Civ. Not even a "what if" scenario. There's a reason Civ IV is considered the pinnacle of the Civilization franchise. They kept adding rather than diverting like the past two games. As others have speculated what Firaxis does in response to other 4X Games etc. They will need to keep an eye out on what Amplitude studios does with Humankind because if they knock it out of the park then... who knows what Firaxis can do.
