This is helping so much. I can get so overwhelmed by world building every little thing, and this has helped me focus my energies. I've written up an entire magical system that previously felt impossible to figure out, just by putting myself in the headspace of a tourist experiencing it. Thank you for coming up with this! I can tell it's going to be a valuable tool in my arsenal of creativity.

Being able to safely become a tourist in my own worlds is massively fun. I've had more fun with Journey than I have with anything else in literally months. This is seriously a dream come true for me. Fantastic work.

If you're a worldbuilder, writer, dungeon master, or just like exploring imaginary places, Journey is a wonderful game about to expanding and expounding on the fascinating details you didn't know you knew about the places you create. I've surprised myself with what I've found and really enjoyed the discovery process.

Luke Miller

Luke Miller is a writer, game designer, and software developer who lives in sunny California with his fiance Roman and their two corgis, Luna and Sol. He has had a lifelong passion for fantasy and science fiction and has recently discovered a love for tabletop roleplaying games.

After exploring the world of TTRPG’s as a player and game master, Luke was struck by the game design bug and quickly jumped into the creation of his first game: Journey. Through this process, he learned many lessons on what to do (and, more importantly, what not to do), and looks to take these learnings into the next game.

In addition to designing his next games, Luke is writing content on the Graycastle Press Journal talking about running tabletop roleplaying games, concepts in game design, writing fiction, and more.
