Mids Meinberg's The Warrior's Journey, is a powerful solo journal RPG that really opened my eyes to how moving the genre can be. This game has some very challenging themes and images. I was skeptical that it was going to pay off. For my money, it does and Meinberg has earned heaps of respect and trust from me for sticking the landing on a fairly brutal game.
Laura Simpson's Companions' Tale is a lovely storytelling game where players draw maps, build cultures, and tell of a hero's quest through the voices of unreliable narrators. The various phases of the game rotate the focus and duties of each of the players, ensuring the world and story feel sincerely communal. Your whole story will play out in one game session.
Moose Trip is a very accessible and beautiful game! Each player to pretend to be a moose that is high on psychedelic mushrooms by responding to prompts from the mushroom feelings table. It's a very simple structure without a too much hand holding, and it relies on the players to just have a chill time with it and negotiate their own experiences.
