To support Geek and Sundry's and Amy Poehler Smart Girl's charity stream which benefited MDA, Matt Mercer, Marisha Ray, Liam O'Brien, Laura Bailey, and Travis Willingham teamed up for a one-shot campaign in the western roleplaying game Deadlands. Audience members were allowed to make donations in order to "buy" Fate chips for players, which had the power to re-roll or add dice to rolls. With a high enough donation, a generous audience member could add a single sentence that could completely change the game.
