I haven't decided what deck I'm using yet, but I've decided that the flavor is going to be 2 songwriters/performers who used to collaborate in some way (in the same band or otherwise) and then had a breakup and went on to do solo stuff. Now they're back for a reunion tour and the setting is an interview promoting the tour.
Initially, the game gives prompts from the interviewer to the artists about their past, but then the at the Turning Point, we start digging into the breakup. I'm also imagining a sort of ending epilogue in which we peek into why they got back together, how the reunion is going, and if it's got staying power (perhaps determined in part or in whole by the rolls of the game).
