Concentrating on the breath is an excellent entry point to a set of much deeper and more interesting experiences.
A video game is not going to lead you to these, because it is too distracting/complex/engaging. The breath can. Boring was perhaps not a good way to express this, but it was simple, without the pull of these subtler sensations being noticeable there is no path forward.
This stream is exponentially less noticeable while doing something less boring, like gaming, to a beginner.
Perhaps "stimulating" is a better concept than "boring" to explain it?
