Banana is one of the funniest things I've had the pleasure of reporting on—it's a game that seems to have started as a joke, but has rapidly skyrocketed to a high throne on the Steam pantheon, becoming the second most-played game on the platform, beaten only by Counter Strike 2.
In case you're unfamiliar, Banana isn't this popular because it's a good game. It's this popular because it offers a stress-free way to gain steam items (Bananas) of various rarity for trade. Essentially think of TF2's hats system, except the game itself only lets you click on a 2d picture of the Spy a lot. Also, you can't wear your hats. That's what Banana is.
