I explained it there, by "nothing else to do" I mean time I can use for hobbies. Or general leisure. Taking a walk, sitting at a park bench, what the fuck ever, can be done with that time, but as I also stated, it keeps circling back to video games being the preferred activity on my lonesome, because it's one I truly enjoy. The other hobbies and activities might be fun for a time, but it's like a honeymoon period; it gets stale after some time or only provides enjoyment in cycles. This hasn't happened with video games for these 26-28 years I've gamed. I may not always be in the mood to game, but that's a momentary thing that last small periods, from hours to a day or few, OR I may be more inclined to check out some Youtube or Netflix at the time. As a hobby video games have still consistently interested me, while all the rest I've tried haven't. I partook in ballroom dancing lessons last autumn, but it began to bore me by February, so I'm on an indefinite "break" from it.
Social interaction is another matter, something I enjoy more than gaming. It counts as "something to do", which makes hobbies unavailable at that time. I instigate gatherings when I feel like it, but I don't always feel like it, I'm not an extrovert. For the rest of the time, I spend on hobbies, which is mainly gaming. Hope that clears your confusion.
