First, photos are non-negotiable. A run with generic avatars dies in the group chat. A run where every tribute has a real photo lives on as the cover image of a TikTok recap. Two minutes spent dragging in photos buys you the entire shareability of the simulation.
Second, read events aloud. The simulator is a spectator format, not a reading format. The same arena event delivered deadpan in a group call gets a five-second reaction loop; the same event read in silence gets a scroll. If you are doing this with friends in person, project on a TV or screen-share.
Third, do not overthink the cast. The viral versions of this trend lean into mess — friend group + their exes + ex hookups + pets + people you hate. A "clean" 24-tribute cast of just your D&D group is less viral than 24 tributes from five different chapters of your life. The unpredictable matchups are the content.
