I was on my phone before. Here's a more complete response.
> that's exactly because they are less stimulating, or to put it bluntly, boring.
Sports are hardly boring, at least if you enjoy the particular sport you're playing. Which isn't true for everyone, so this is one that can be dropped off a lot of people's lists.
Going outside can often be stimulating, if you're open to it. I don't get to do it as much as I'd like, but camping or at least hiking is fun. I went to a friend's wedding in November in a state park. I stayed at the lodge in the park and from my window I had a fantastic view of the trees in their autumn colors, blanketing the mountains. A friend and I hiked a few miles of trails, seeing the waterfalls and river from various angles. A very memorable and enjoyable experience. My only regret is that my girlfriend couldn't make the trip, but it gives me something to show her in the future. And then there's stargazing, or catching rare or uncommon events like a lunar eclipse or a total solar eclipse. I still remember the time in high school my dad snagged a couple pairs of night vision goggles and drove us out to the middle of the desert to watch a meteor shower. That was 15 or so years ago and the memory is still strong in my mind.
Dating is hardly less stimulating than games. I've, admittedly, not got much experience because, well, my 20s were wasted. But, I've never experienced this level of fear and exhilaration and happiness all rolled into one moment in anything other than dealing with someone I loved.
Hanging out with friends is a broad thing. While not video games, my friends and I play boardgames, card games and tabletop RPGs. For me, I count these as distinct from video games because they require enough effort to setup and play that they can't touch the addictiveness of video games. We also go to the nearby big (hah!) city's downtown and have a good time checking out local productions of plays and art by local artists at the galleries. Eating at restaurants with interesting cuisine. All these things are stimulating, and to a variety of senses. And it's a shared experience with people I care about and that care about me, making it an emotionally satisfying experience.
