TBF gacha is best described not as a genre, but rather as a dark mechanic designed to promote a psychologically exploitative stimulus/reward system as a revenue increasing measure. In much the same way as Arcade Games are designed to counter 1-credit completion, or how console games later augmented playtime to surpass a standard weekend rental window, Gacha is something that compromises genres rather than defines one.
