Dubious Pursuits from Nested Games is a really elegant 1-Move RPG about being a bounty hunter.
The reason it's elegant, is that the move receives a mechanical bonus to it's die roll as you learn more about your bounty, meaning that single move also has the mechanics for plot propulsion built into it.
It's a roll to answer a question move; your role gives you additional questions (again, elegantly) that you may ask.
There aren't many one-move games that I'd play - often they are more lyric than sit-around-the-table fare. This, however, is definitely one of them.
Dubious Pursuits, Five Stars!
