Addiction happens in whatever games, what we call Addiction is an uncontrollable urge for something, and an addict, does that thing he is addicted to consistently, so it doesn't matter which game, addictions can come from whatever games be it slot, dice, sport betting and the rest.
Addiction is about the state of mind of the addict and not what he addicted to, a gambling addict can play several gambling game2all fuelled by his addictions.
Wiwo you are right, no game cause more addiction, the game that may cause you addiction may not cause me addiction is just based on our mind and thinking.
Just like you said that Addiction is about the state of mind of the addict and not what he or she is addicted to, meaning your addiction is caused by your state of mind you allowed which ever game get into you.
Some times I see people saying people should avoid gambling because it causes addiction and I ask is it only gambling that people get addicted to the answer is no, some people get addicted to video games, when I was in the university I have a roommate then in my hostel, he was so addicted to video games that going to classes was a big problem he can stay from morning till night playing video games and he was spending a lot of money doing that, so is not only gambling that people get addicted and is not the kind of gambling you play is your mentality, for me no kind of game I will play that will make me become addicted to it, I hate addiction and once I discover I'm doing something too much I stop it immediately, I like being in control of my own self not something controlling me.
