So yeah, I think the phrasing is pedantic, but I do think it is possible to an extent.
I think wording is very important, so I personally don't consider it pedantic. I mean I love and agree with all the responses so far, but I wouldn't categorise any of the examples given as "having grown out of', they're simply changes in situation as far as I can see, ones that just so happen to coincide with what's....I guess, almost 'expected' of us as we get older. While I don't really expect to hear it from many people here, I do still believe there is a general stigma out there still that views gaming as something almost childish that you'd expect to one day give up on naturally. I've seen a couple of my friends wives make such comments about their husbands gaming activities, and while you could be thinking that it is simply the time being wasted that they are referring to, this was much more of an expectation that someday they are going to … well, grow out it, and I don't see the same comment being made if they spent a similar amount of time watching TV, they'd get a comment sure, but not the same one lol.
In a hypothetical scenario, where you had no need for a job, lived alone and had exactly the same commitments you had when you were a teenager, do you think you're view on and passion with gaming would likely change as you got older?
