But again, splitting hairs into dopamine rush versus actual fun is simply semantics. Fun = dopamine rush. Does it matter if you are cognizant of the fun, or do the chemicals matter?
To be clear, I am 100% in agreement with you. Most mobile games (and honestly, most pc games at this point with their item and resource gathering mechanics; and I am absolutely talking about MMO's - there's a reason many many many franchises are working toward a multi-player experience instead of focusing on the single player game) aren't supposed to be 'fun'. They're supposed to be addictive, and I believe it is a real problem, especially for kids growing up learning that a dopamine hit is just one iphone game away.
Anyway, though, I guess my point is - it's all semantics. When you say, it's not 'fun', it's just a dopamine rush, developers and sales people can say that's just the same thing. They can argue that people wouldn't play unless they received some kind of value out of it.
To be honest, I've forgotten where I started with all this, other than to say - when you have to split hairs on the definition, it leaves room for people to interpret their own meaning and ignore nuance. Therefore, this is an argument that people don't want to hear, engage with, or consider, I believe.
