I've got a pet peeve and a more substantive complaint. The peeve is when I see those dumb "three match" games advertised on Facebook that involve trying to save someone from a wall closing in on them, and then when I download the game it doesn't even have the scene that they're advertising.
But the more substantive complaint is the way games like this proudly advertise how "addictive" they are. I feel like we have turned addiction into such an abstraction that we've forgotten it is a serious issue with real-life consequences. Whether it's cigarettes, drugs, gambling or our phones, addiction has a massively negative impact on our society. The idea that a game-maker is actively bragging about its attempt to rewire our brains in order to get us to engage in harmful activities is pretty appalling when you think about it.
Invariably, whenever I do download one of those games, I waste a ton of time playing on it in the first 24 hours, constantly telling myself I will stop after I finish my current game, before finally deleting it off my phone because a) I recognize the problem is only going to get worse, and b) it makes me very concerned about what I would do if, God forbid, I ever got hooked on something more dangerous like heroin
