It isn't about saving the world or leveling up a character for hundreds of hours. It is about the simple geometry of a bowstring, the arc of an arrow, and the fleeting satisfaction of hitting a target 50 virtual feet away. In a high-stress environment like a classroom or a cubicle, that simple act of focus is often exactly what the player needs.
The game's simplicity and the ability to play it without significant distractions or complicated controls make it highly accessible.
