Given: A group of trad/computer RPG players who are willing but lack much experience in improv or storygames.
Goal: To ramp up to playing more "story-first" and "bleedy" games, with more player agency, character depth, immersion, etc.
Prescription: As a group, we want to learn immersion techniques, develop improv capabilities, and increase interpersonal trust.
Various types of improv exercises (and certain full-fledged games) are easy and effective ways to enhance the storytelling effectiveness and internal trust of a gaming group. I'm interested in hearing some of your recommendations. Keep them simple. No rules over 2 pages. No games over 1 hour. What I'm really looking for here are things that might fall somewhere between a "game" and an "exercise".
