In many ways this is everything I hate about games. A dopamine loop shorn of any meaningful context or decision making. Numbers go up and shit dies but since you have so few ways to meaningfully interact with the game besides choosing what rewards you select it just ends up being a totally empty treat-treadmill. As a result, it is engaging in the worst way possible, somewhat similar to the mindless engagement one gets from playing a slot machine. It is utterly meaningless from every angle, and the only reason I don't rate it any lower is because it at least has the decency to not rob people blind with microtransactions, even if it robs them of their time.
