"The Big One" is going to be an open world RPG where the genre of play changes based on how you invest in the game's tech tree. This prototype was built to test out the first pillar of the game, which is that "The world does not care about you until you make it care." Nations build armies, nature creates monsters, and the world chugs along without you until you become strong enough that the world cannot ignore you anymore.
