It is society that is making it hard for game players to stop playing. As a long time player let me explain why.
I hate games that use RNG as a difficulty crutch (some rouge likes), gambler logic (loot boxes), and Feed and Starve (candy crush/pay for lives/continues) to hook me. Why ? because it makes me angry when playing their games because I know what gambling is and how it works on the mind, but more importantly, because I am looking for MORE from my game than simple risk/reward gimmicks.
It would be interesting in a study to see if people with more developed intellectual capacity fall for these game types than people who have not cared to develop their intellectual capacities. I admit that I believe that some people are hooked on these games because they either do not care or are shallow enough to allow their time to be used in this way.
That said, I think the distinction in such a study needs to be on people that actually have some form of addiction. It does not need to be major, but enough of one where it is clear that their gaming habits are at least noticeably affecting their work/friend/love/life balances.
People who play these games just to pass the time as they move from moment to moment in life should not be considered, regardless of the types of games they play. They are clearly immune or are able to see these gimmicks for what they are.
As a gamer myself, I hate most MMO's as a never ending grindfest, mobs stand around like cattle, bosses never really die, the environments are not really changeable by the players actions, though so mmo's try to emulate this with updates. I mean nothing says it more than... go kill 10 slimes and return here. Or running the same stage over and over and over ad nauseum where one mistake can lead to disaster and angry people because game balance in MMO's always mean as a single unit you are never strong or capable. Sure teamwork is nice but if those monsters are really that strong how can the popoulations the players represent live in those worlds? O right, I forgot, bosses are immortal, over sized and never have to leave their lairs and just happen to have mobs of defender acolytes for what reason again?
I liked terraria for the exploration, world modification, and creative boss fights, though I do not think the boss fights are really balanced.
I liked factorio for its complex crafting and logic gameplay, but mobs on even the hardest configurations are pie cake to deal with and at best annoyance.
I very much appreciate games that provide at least semi plausible reasons for things going on, not just being used as plot devices or macguffins.
it is my opinion that because society is more about giving people knowledge without actually attempting to teach them "why" that knowledge if valuable, they waste it or misunderstand it leading them to become easily suckered by so many things... least of which is a game with mechanics so simple that only a simple mind can enjoy them! Or in short, shallow risk reward mechanics! People who require "deeper" and "more meaningful" experiences are busy doing something else because these games are just too shallow to hold their attention.
So can you really blame game developers for figuring out how the simple minded tick? Nope! Just give them their money, they earned it! Or rather, they earned tricking it out of their pockets!
