About Pax Historia
Pax Historia is an AI powered sandbox game where players create and upload whatever worlds they can imagine for others to play. What if Rome never fell? What if aliens invaded Earth? What if you were a college dropout creating a tech startup? The ability to create, edit, and copy custom maps, actors, historical context, and more means that users can play nearly any scenario they can imagine. We've organically built a passionate fanbase of tens of thousands of daily active players and we're excited to expand on this early start. Consider joining us to help build vastly better tools for creators and experiences for players.
