Youhou ! is the french translation of Yowl! by Tyler Magruder,
a Play by Review game of bizarre places.
It’s super accessible and fun, and you should check it, in one language or another. It would take you longer to read about the game than to read the game itself. It’s all in the previews or, if you need better quality, through Shared copies (they are for everyone).
Let’s say it’s a collaborative writing game a la SCP, but so much lighter.
