@phase-face This is a story-driven game, and we want players influencing the game through story. If the Brotherhood is being hunted down by the Avengers, the X-Men can choose to intervene to protect them, for example, or do their side of the plot. Maybe a X-Man slips to a SHIELD agent that Xavier's is the home of the X-Men, and that will have consequences too.
The idea is that the Brotherhood and the X-Men, although opposed in many ways, are still together in the 'we are all mutants' front. Our storytellers are here to provide the opposition, be in the form of the Avengers, Apocalypse, Marauders, Sublime or what have you.
In general, our plots will aim to provide both sides with different approaches that will have consequences if done one way or another. If players don't react, then we will provide an 'all things remaining constant' scenario and go from there. We want these ideologies, and how these characters live them, individually, to have an impact in the story. This is why the Pitch comes first. It is the most important step of the app process.
