A Freeform LARP
From the introduction:
Stay, Still is a post-apocalyptic storytelling game about giving a stronger voice to the supporting characters in popular media, and about the difficult choices we need to make to survive. It is a free-form larp for a small group of people interested in peaceful arguments, collaboration, and speaking in code.
This commercially published game is a revised, updated, and expanded version of an eponymous Game Chef 2015 finalist game.
