If you're looking into the comments unsure of the game let me just tell you: buy it right now. Do not even claim the community copy, go pay the 12 bucks, it ain't much and it's absolutely worth your money.
One of the best gm-less storytelling/worldbuilding games my group has ever played. We went for the Count of Saint Lazare playbook (because otherwise we would get stuck on worldbuilding for 2 hours, thank you for the option) and it was an absolute blast. I really liked the amount of flexibility even the premade world and characters allowed, each of the players had a Conspirators who was vile and detestable in the exact way they enjoyed (Pierre-Voclain yoU BASTARD). Prompts were fun, structure was great and art was inspiring. The only suggestion I could really give is that some of the epilogue questions assume the Conspirators to be still alive and yet it is impossible to reach the end without feeling a deep need to kill all of them off, thus rendering the choices for questions quite limited (mostly suggesting it as a joke but it was an actual issue my group encountered lol). My friend already suggested we play Arcadia Prime with a slightly different group in the near future and I cannot wait.
PS: Appreciate the Miro board. It is absolutely stellar. The single best one I've seen for any rpg so far.
