The City Is As Stars is a two-page, one-player rpg where you connect to other people by looking at city lights at night and imagining what's on the other side of them.
It's very simple, but the writing is lovely, and it does a good job at giving you a sense of interconnectedness with other people.
If you like concept-games, or lyric games, or other games-as-poetry type stuff, I think you'll like this. Similarly, if you like games as meditation exercises or ways of re-framing your thinking, it's worth picking up a copy of City.
