I have really enjoyed this game so far! The questions are evocative, but open enough that it doesn't lead you to one particular setting or world; each player can add on and build more with their answers as well. You only have to decide whatever a question asks about your character, building as you go, but you can use this with pre-built characters or characters built as a group prior to going into the prompts. While I have had some groups interested in playing this type of game by roleplaying out each prompt as a group, I have also had groups more interested in "parallel" play where each player takes their own prompt in turn - this works great for a pbp format too. Some of the prompts are pretty dramatic, which I love!
