Knowing You is a 14 page, two player rpg about diving to the bottom of a relationship that has already been horribly shattered and will not be repaired. It is played by answering questions in a structured format. It also has the potential to get real personal if you accidentally or intentionally drag any of yourself into it, and I would urge significant caution there.
The layout is really cool, positioning the content as a text conversation, and the pdf is really easy to read.
The writing is also solid, and the questions really dig into the nature and nuance of the relationship.
I think if you like tragic games about relationships, this is a tight, focused experience. If you do not want to go through the simulated emotional crash and intense what-if-ing following a bad breakup, you probably do not want to play this.
