While the end result might be the same, there seems to be a much clearer intent to create addiction in some parts of the game industry, especially where gaming and gambling meet.
It's not surprising lawsuits about porn addiction aren't going ahead when it's so easy to get an expert witness to (truthfully) testify that the psychiatric profession doesn't recognise porn addiction as a real thing.
There's certainly people consuming porn who'd like to consume less, and who believe their consumption is harming their lives. That doesn't mean addiction is the correct model for what's going on, and to date, there appears to be little-to-no evidence showing that it is.

Excerpt:
> Carlat: How did you decide on five criteria as being your minimum threshold for depression?
> Spitzer: It was just consensus. We would ask clinicians and researchers, “How many symptoms do you think patients ought to have before you would give them a diagnosis of depression?” And we came up with the arbitrary number of five.
> Carlat: But why did you choose five and not four? Or why didn’t you choose six?
> Spitzer: Because four just seemed like not enough. And six seemed like too much.
