What an awkward necro.
If someone had been born the day I first posted in this thread, they would now be older than I was when I made that post.
TTRPGs are an engaging hobby because they engage a lot of different ways of thinking and being creative at once, and I'm be hard pressed to name another activity that has a similar mix. While there are certainly dangers associated with engaging with fantasy too much or in lieu of other activities, there are certainly worse hobbies and vices to delve into. It would take much more extreme behavior for me to think that someone has gone too far with elfgames than, say, gambling.
To this day I spend a significant amount of my free time dealing with TTRPGs. From prepping for sessions, to worldbuilding, to actually running the game. But I have a full time job, maintain a (admittedly minimal) social network, and engage in other hobbies. It doesn't consume my life and I can easily talk and relate to people who don't game, which I think is an indicator of a healthy relationship with the hobby.
